Specific gravity of stainless steel 12x18n10t - sovetskyfilm.ru

“Stainless” in engineering usage refers to a fairly large group of steel grades, which includes several groups of steels with specific properties that are not limited to rust resistance alone.

For example, the most common grades of stainless steel, such as 12Х18Н10Т and 12Х18Н12Т, belong by purpose simultaneously to corrosion-resistant steels, heat-resistant, cryogenic and structural steels, and in terms of chemical composition, respectively, to groups of steels with the addition of chromium, nickel and titanium.

To perform certain types of work, it is necessary to take into account quality characteristics materials. Stainless steel, as one of the most popular types of rolled metal, has a different chemical composition, mechanical and other properties that determine it practical use.

Methods for calculating the weight of stainless metal

To calculate the specific gravity of stainless steel, a standard formula is used. The ratio between the mass and volume of stainless steel metal will be its specific gravity.

In turn, to calculate the mass of rolled products, the available specific gravity is multiplied by the area cross section rolled product and its length.

Let's look at specific examples of calculating the weight of stainless steel:

Example 1. Calculate the weight of circles with a diameter of 50 mm made of steel 12Х18Н10Т with a length of 4 meters, in the amount of 120 pieces.

Let's find the cross-sectional area of the circle S = πR 2 means S = 3.1415 2.5 2 = 19.625 cm 2

Let's find the mass of one rod, knowing that the specific gravity of the 12Х18Н10Т brand = 7.9 g/cm 3

M = 1&.6259middot;4009middot;7.9 = 62.015 kg

Total weight of all rods M = 62.015 120 = 7441.8 kg

Example 2. Calculate the weight of a pipe with a diameter of 60 mm and a wall thickness of 5 mm made of steel 08X13, 6 meters long, in the amount of 42 pieces.

Let's find the cross-sectional area of the pipe, to do this we determine the cross-sectional area of the pipe as if it were a circle and subtract the area of the internal empty space

S = 3.1415 3 2 - 3.1415 2.5 2 = 28.2735 - 19.625 = 8.6485 cm 2

Therefore, with a specific gravity of grade 08Х13 = 7.76 g/cm 3, the mass of one pipe will be

M = 8.6485 7.769middot;600 = 40.267 kg

In total, all pipes weigh M = 40.267 42 = 1691.23 kg

Example 3. Calculate the weight of sheets with a thickness of 2 mm and a cutting size of 500x500 mm made of steel 15X25T, in the amount of 6 pieces.

The volume of one sheet is V = 2 5009middot; 500 = 500000 mm 3 = 500 cm 3

Sheet weight based on the specific gravity of grade 15Х25Т = 7.7 g/cm 3

M = 500 7.7 = 3850 grams = 3.85 kg, therefore

Total mass of all rolled products M = 3.85 6 = 23.1 kg

Stainless steel can be classified

1. by microstructure,

2. by chemical composition,

3. by method and type of production,

4. by scope of application.

Below are data on the specific gravity of some of the most common types of steels, which are calculated using this formula:

The inclusion of various chemical elements in stainless steel makes it possible to improve some of its characteristics:

Impact strength,

Anti-corrosion resistance,

In addition, manganese, aluminum, chromium and carbon reduce the specific gravity of stainless steel, while nickel, tungsten and copper, on the contrary, increase it. You can find out about its composition by looking at the labeling.

The scope of application of stainless steel is difficult to overestimate, since there is not a single industrial or domestic area where it is not used in one form or another. Medicine, food industry, electronics, electric power industry, Appliances, automobile and mechanical engineering, chemical and oil and gas industries, construction - in each of these industries stainless steel is in demand because it combines unique characteristics.

Possessing unprecedented anti-corrosion and antioxidant qualities, stainless steel is urgently needed in the food and pharmaceutical industries. Thanks to it, it is possible to maintain the purity of the chemical composition food products and medicines, the organic elements of which do not react with “stainless” materials; elements of equipment, tools and special containers.

In construction, structures made of stainless steel can reduce the load on the capital foundation. The construction of multi-story high-rise buildings became possible thanks to stainless steel structures.

Speaking about the practical value of stainless steel, we must not forget about its aesthetic characteristics. The appearance of stainless steel products is so impressive that this material is now actively used by architects and designers, not only to impart structural strength, but also as decorative elements.

To calculate the mass of stainless steel by specific gravity, there is a special metal calculator.

The density of stainless steel, like other metals, as well as materials and substances, is a characteristic whose existence many do not even suspect, having long forgotten almost everything they studied in physics lessons at school. Meanwhile, anyone who needs to know the exact weight of rolled metal from high-alloy alloys cannot do without this parameter.

Density of 12Х18Н10Т and a number of other common stainless steels

Density (P) is a physical quantity that is determined for a homogeneous material or substance by its mass (in g, kg or t) per unit volume (1 mm3. 1 cm3 or 1 m3). That is, it is calculated by dividing the mass by the volume in which it is contained. The result is a certain quantity, which for each material and substance has its own value, varying depending on the temperature. Density is also called specific gravity. Using this term, it is easier to understand the essence of this characteristic. That is, it is the mass possessed by a unit volume of a material or substance.

Specific gravity of stainless steel

And to calculate the theoretical (calculated nominal) weight of 1 linear or square meter For any metal product, this physical quantity is used - density, of course, for the corresponding metal. And in all GOST standards for the assortment, where the main characteristics of rolled products are given, after the tables that list the theoretical masses of 1 linear or square meter of products of different standard sizes, it is necessary to indicate exactly what density value was taken in the calculation. Why and when you need to find out the weight of 1 meter of metal products. everyone who needs it knows it. This parameter is used to calculate the total mass of one product or an entire batch based on their total length or area. But why and when do you need to know the density of steel, in particular stainless steel?

The fact is that for all types of metal products, the theoretical mass of 1 meter given in GOSTs and reference books was calculated using one or another average density value. For rolled steel, the most common indication is 7850 kg/m3 or 7.85 g/cm3, which is the same thing. And the actual P of steel, depending on the alloy used for the production of the product, can vary from 7600 to 8800 kg/m 3.

If you wish, it is easy to calculate what the error will be if you calculate the mass of a corner (or a product of another type of rolled steel) made not from carbon or other steel with a density of 7850 kg/m3, but from another heavier one (for example, steel 12Х18Н10Т) or light alloy. For small volumes of rolled products, and when precise determination of weight is not required, the difference will be insignificant. That is, an approximate calculation of the total mass of metal products based on tabular data from GOST on the weight of 1 meter will be justified. In addition, during shipment, as a rule, weighing is done to determine the actual weight of the products for the accuracy of mutual settlements between the supplier and the buyer.

The density of steel 12Х18Н10Т and some other most common stainless alloys is indicated in the tables below. In the last column of the tables, the approximate coefficient relative to the density is 7850 kg/m 3 (7.85 g/cm 3).

Stainless steel is an alloy steel that is resistant to corrosion in harsh environments and atmospheres. This type of steel is divided into three groups: corrosion-resistant, heat-resistant and heat-resistant. These groups are specifically divided to solve specific problems.

Thus, corrosion-resistant steels are used where high corrosion resistance of materials is required, as in living conditions, and in industrial work. Heat-resistant steels are used in situations where good resistance of the material to corrosion under high temperatures is required, for example, in chemical plants. Heat-resistant steels – where high mechanical strength at high temperatures is required.

When working with stainless steel, it is extremely important to know the quality indicator. A characteristic such as the specific gravity of stainless steel will help you determine this parameter.

Stainless Steel Specific Gravity Table

Below is a table of values that will help you carry out everything necessary calculations when working with stainless steel, including the weight of the stainless steel.

Specific gravity and weight of 1 m3 of stainless steel depending on units of measurement

From 7650 to 7950

Specific Gravity Calculations

In order to carry out all the necessary calculations, it is necessary to determine the very concept of this characteristic. So, specific gravity is the ratio of weight to volume of the desired material or substance. Calculations are carried out using the following formula: y=p*g, where y is specific gravity, p is density, g is the acceleration of gravity, which in normal cases is a constant and equals 9.81 m/s*s. The result is measured in Newtons divided by cubic meter (N/m3). To convert to the SI system, the result is multiplied by 0.102.

Density is the value of mass required material or a substance measured in kilograms that fits in a cubic meter. It is a very ambiguous value that depends on many factors. For example, temperatures. So, the density of stainless steel is 7950 kg/m3.

In addition, during shipment, as a rule, weighing is done to determine the actual weight of the products for the accuracy of mutual settlements between the supplier and the buyer.

But it is often necessary to know the exact, albeit theoretical, weight at the stage of placing an order for the supply of rolled products, and for design and project calculations this is prerequisite. It is in such cases that the density of the alloy from which the metal product is made is determined, and then, based on these data, an adjustment is made to the mass of 1 meter taken from GOST. And only then the total weight of the rolled product is calculated. How to adjust the weight of 1 meter is discussed below.

Why calculate the density of rolled metal? Most likely you will never need this. However, circumstances may arise where calculating density may be the only quick in an accessible way, which allows you to approximately determine which group of alloys (steel grades) the metal from which the unmarked product of interest is made belongs to. In accordance with the above definition of density, calculating it for an alloy of a particular rolled product is quite simple. You need to divide its mass by its volume. The first value is determined by weighing, and the second is calculated after measuring all the required dimensions of the product.

One way to calculate steel density

Correcting the theoretical mass of 1 meter of rolled steel taken from GOST tables or reference books is also quite simple. It is necessary to divide it by the density, which is indicated in the standard or reference manual used, usually before or after tables with product sizes. As a rule, it is written there that the density of the metal is assumed to be equal to such and such a value. Then we multiply the obtained value by the actual P of the alloy from which the product of interest is made.

You can also use a conversion factor for adjustment, obtained by dividing the actual density by that used to calculate the theoretical weight of 1 meter.

It is given in a number of GOSTs and reference books for some grades of alloys. In this case, it will be enough to multiply the theoretical mass taken from the standard by this coefficient. However, it must be borne in mind that such an adjustment will be less accurate than when using the previous method, since the coefficients are approximate due to rounding to hundredths.

Physical characteristics of stainless steel AISI (GOST). Calculation of weight and density of stainless steel products. |

The main physical characteristics of stainless steel, which are taken into account when designing stainless steel products and structures, are the mass of the unit of measurement (linear meter) and density. This article will help you understand this issue, and the tables below will help you make the necessary calculations.

Calculation of the weight of stainless steel

Formulas that we know from a school physics course will help you calculate the weight of stainless steel of any steel grade (aisi, or GOST). To make the calculation, you need to know the geometric dimensions and density of the steel grade from which this product is made. By multiplying the cross-sectional area by the length of the product and the density of the steel, we get the weight of the stainless steel.

Below are the most simple formulas for calculating the mass of stainless steel: circle, round pipe, sheet. To calculate the mass of more complex shapes (hexagon, angle, stainless profile pipe or I-beam), you can use a metallurgical calculator or special tables.

Calculation of the mass of a stainless steel circle (rod):

To convert to kilograms, the result must be divided by 1000.* The calculation of the weight of the stainless pipe and circle is made for 1 meter, in order to obtain the total weight of the meter you need, you need to multiply the result by l.

Density table

Density is the mass of a substance per unit volume. Due to their chemical composition (low or high content of carbon and alloying elements), different grades of stainless steel have different densities. The density of stainless steel must be taken into account when calculating the mass of stainless steel that will be used for your purposes.

sheet, Aisi 304 and 430

The use of stainless steel is very common today in many industries. Among them are the construction of buildings, both industrial and residential. Automotive, aircraft and shipbuilding also cannot do without the use of this metal. The price of steel sheets and pipes on sale is always indicated per kilogram.

Why is specific gravity needed?

When conducting construction work it is necessary to calculate the weight not only in order to purchase the required amount of material, but also to determine what the load on the support will be.

The specific gravity of stainless steel is the main characteristic of the metal, allowing the necessary calculations to be made. Knowing this parameter, you can use special calculators and programs to determine the mass of the material. The specific density of steel ranges from 7700 to 7900 kg/m3.

Calculate the mass of the pipe

length;
diameter;
thickness;
specific gravity.

Using the tables, you can select the required ratio of pipe length and diameter. You can calculate the mass of a product by multiplying its volume by its density. Accordingly, to calculate the volume, you need to multiply the value equal to the wall thickness by the surface area. In this case, the area is determined as the product of pi, the length of the pipe and its diameter.

For example, if you need to determine how much it weighs steel pipe grade 12x18n10t, the length of which is 10 m, diameter 10 cm, and wall thickness 1 mm, the calculation procedure will be as follows:

the specific density value of 7900 is multiplied by the diameter: 7900*0.1=790;
multiply by the length and thickness of the wall: 790*10*0.001=7.9;
multiply by a constant value of “pi”: 7.9 * 3.14 = 24.81 (kg).

However, these calculations may not be very accurate. This is determined by the round surface of the pipe.

You can also use another formula; it is a more simplified version and is used to calculate the linear meter of the product.

To determine the mass, you need to subtract the wall thickness from the value that determines the diameter of the product. The resulting value is multiplied by the wall thickness and the value 0.025. IN general view the formula looks like this:

1 p.m.= (D-T)*T*0.025

Then a linear meter of the same pipe will weigh 2.475 kg. Although the difference in the numbers obtained is negligible, you should purchase slightly more material than calculated to account for cutting and processing costs.

Sheet material

It should also be taken into account that stainless steel includes a large group of grades of this metal. The most common brands are: 12x18N10T, 08x18N10, and also 12x18N12T. Foreign analogues are also popular, among them Aisi 321, Aisi 304 and Aisi 430. All these brands are characterized by high degree corrosion resistance, ease of processing, high strength.

The material can be thin-sheet or thick-sheet depending on the type of rolled product. Thin-sheet products are those having a thickness of 0.5-5 mm. For thick sheets, this number is 5-50 mm.

The most common sheet sizes are 1000x2000 mm, 1250x2500 mm, 1500x3000 mm. The weight of a stainless steel sheet is somewhat easier to calculate than the weight of a pipe.

To calculate the weight of a stainless steel sheet, you need to multiply the height, thickness and width. In general required amount material can be calculated by multiplying the mass of one sheet by the required number of sheets.

For example, the weight of stainless steel 12x18n10t for a sheet measuring 0.5x1000x2000 mm will be about 8 kg. A sheet of the same size, but with a thickness of 1 mm, will already weigh 16 kg.

To determine the mass of sheets, you can use special theoretical tables or a calculator.

Railings and fences

Stainless steel due to its properties and attractive appearance very often used to create stair railings and fences. Often, products made from this metal are used by designers and architects as decorative elements. It is necessary to know the weight of structures when transporting products in order to calculate the expected load on the base of the railing. Knowing the above formulas, the calculation process is greatly simplified.

For example, average weight fences or stair railings will be approximately 5-6 kg. If the presence of glass sheet is assumed in the design of the fences, the weight will exceed 20 kg. When planning the transportation of parts, you should consider not only how much they will weigh, but also the length of the products. In the photo you can see examples of the use of this metal.

Steel 12Х18Н10Т. Characteristics, application and explanation

Stainless steel 12Х18Н10Т is characterized by durability, environmental friendliness and safety. She has certificates confirming technical indicators in accordance with Russian and foreign standards.

Popularity in many industries due to high performance qualities, big amount advantages, as well as low cost. The ease of machining and a variety of welding methods make it possible to create structures for various purposes, as well as use the material almost everywhere.

Structural cryogenic steel 12Х18Н10Т is austenite, it is produced by melting in electric arc furnaces. This manufacturing method ensures resistance to corrosion due to the unique crystal lattice, as well as the ability to maintain its characteristics at temperatures up to 800 degrees Celsius. The material is subjected to cold rolling and heat treatment.

Thus, corrosion-resistant steels are used where high corrosion resistance of materials is required, both in domestic conditions and in industrial work. Heat-resistant steels are used in situations where good resistance of the material to corrosion under high temperatures is required, for example, in chemical plants. Heat-resistant steels - where high mechanical strength at high temperatures is required.

When working with stainless steel, it is extremely important to know the quality indicator. A characteristic such as the specific gravity of stainless steel will help you determine this parameter.

Stainless Steel Specific Gravity Table

Below is a table of values that will help you carry out all the necessary calculations when working with stainless steel, including the weight of stainless steel.

Specific Gravity Calculations

In order to carry out all the necessary calculations, it is necessary to determine the very concept of this characteristic. So, specific gravity is the ratio of weight to volume of the desired material or substance. Calculations are carried out using the following formula: y=p*g, where y is the specific gravity, p is the density, g is the acceleration of gravity, which in normal cases is a constant and equals 9.81 m/s*s. The result is measured in Newtons divided by cubic meter (N/m3). To convert to the SI system, the result is multiplied by 0.102.

Density is the value of the mass of the required material or substance, measured in kilograms, that fits in a cubic meter. It is a very ambiguous value that depends on many factors. For example, temperatures. So, the density of stainless steel is 7950 kg/m3.

When carrying out construction work, it is necessary to calculate the weight not only in order to purchase the required amount of material, but also to determine what the load on the support will be.

Calculate the mass of the pipe

length;
diameter;
thickness;
specific gravity.

For example, if you need to determine how much a 12x18n10t steel pipe weighs, the length of which is 10 m, the diameter is 10 cm, and the wall thickness is 1 mm, the calculation procedure will be as follows:

the specific density value of 7900 is multiplied by the diameter: 7900*0.1=790;
multiply by the length and thickness of the wall: 790*10*0.001=7.9;
multiply by a constant value of “pi”: 7.9 * 3.14 = 24.81 (kg).

However, these calculations may not be very accurate. This is determined by the round surface of the pipe.

You can also use another formula; it is a more simplified version and is used to calculate the linear meter of the product.

1 p.m.= (D-T)*T*0.025

Stainless steel sheet

Stainless (alloy) sheet steel is resistant to all types of corrosion, due to which its use can reduce the weight of metal structures, extend the service life of objects and significantly reduce the cost of their operation and maintenance.

Moreover, it should be noted that not all corrosion-resistant and heat-resistant steel grades are stainless. Stainless alloys include alloys containing alloying additives from 10 to 50%: chromium 12-26%, nickel 8-21%, molybdenum 1-3%, titanium 0.7-0.8% (the percentage depends on the type of stainless steel: ferritic, martensitic or austenitic). The most popular Russian grades of stainless steels, which have foreign analogues, include steels of the 300 series: AISI 304 (08Х18Н10), AISI 316 (10Х17Н13М2), AISI 316T (10Х17Н13М2Т), AISI 321 (08-12Х18Н10Т).

Types of stainless steel sheets

Alloy steel sheets are divided into hot-rolled and cold-rolled. Both types of rental are classified according to:

rolling accuracy (A and B);
type of edge: trimmed and unedged (O, BUT);
sheet flatness group (PO, PV, PU, PN).

Hot-rolled stainless steel has a wide size range and affordable cost, which explains the scale of demand in various fields: mechanical engineering, construction, production of equipment for the food, chemical, oil refining, pharmaceutical industries, etc. According to the quality of surface treatment, hot-rolled steel is produced:

without additional heat treatment(5d);
bright annealed/heat treated, etched (M2b, M3b, M4b, M5b).

Cold-rolled sheets made from stainless steel grades are produced in a small thickness (the maximum thickness of a cold-rolled sheet is 5 mm, when a hot-rolled sheet is ten times larger - 50 mm). Thanks to additional processing, cold-rolled steel has improved surface quality and additional strength (as a result of reduced deformation stresses). According to the type of surface treatment, cold-rolled steel is:

hard-worked (H1);
semi-hardened (PN1);
etched or treated with light annealing (M2b, M3b, M4b, M5b).

Thickness of rolled sheets made of corrosion-resistant and heat-resistant steel grades

Rolled stainless steel sheets come in thin and thick sheets.

Rolled thin sheets made from alloy steel grades in accordance with technical specifications according to GOCT 5582-75. Standard range of sheet steel thicknesses:

hot rolled from 1.5 to 3.9 mm in increments of 0.1; 0.2; 0.3 mm;
cold rolled from 0.5 to 3.9 mm in increments of 0.05; 0.1; 0.2; 0.3 mm.

Thick stainless steel sheets manufactured according to technical specifications according to GOCT - 7350-77. Standard range of thicknesses of thick alloy steel:

hot rolled from 4 to 50 mm in increments of 0.5; 1; 2; 3 mm;
cold rolled from 4 to 5 mm in increments of 0.2 and 0.3 mm.

Stainless steel sheet sizes

The size range and permissible maximum deviations for stainless steel sheets are established depending on the thickness of the sheet (thick or thin sheet steel) and the production method (hot-rolled or cold-rolled steel).

The size range of hot-rolled stainless steel is regulated by GOCT 19903 (for thicknesses defined by GOCT 7350-77 for thick sheet steel and GOCT 5582-75 for thin sheet steel).

The size range of cold-rolled stainless steel sheets, just like hot-rolled ones, depends on the standard thicknesses and production method: the thickness range is regulated by GOCT 5582-75 (for thin sheets) and GOCT 7350-77 (for thick sheets), and standard sizes The length and width of the sheet, depending on the thickness, are established by GOCT 19904. Moreover, the range of the size range of cold-rolled steel is significantly inferior to the range of hot-rolled steel:

for thin-sheet rolled products, sheet width is set in the range from 500 to 1800 mm, length from 1000 to 6000 mm;
for thick sheets, sheet width from 1250 to 2350 mm, length from 2000 to 4750 mm.

Weight of stainless steel sheets

The weight of a sheet of any size made of stainless steel of a certain grade is calculated by the formula:

M = ρ×a×l×h, where:

M - required weight, kg;
ρ - specific gravity of stainless steel, g/cm³, tabular value;
a - sheet width in meters (m);
l - sheet length in meters (m);
h is the sheet thickness in millimeters (mm).

For example, a hot-rolled thick sheet made of steel grade 08Х18Н10Т (ρ = 7.90 g/cm³), 1420 mm wide, 6000 mm long and 4 mm thick will weigh:

M = ρ×a×l×h = 7.90×1.42×6×4 = 269.232 kg
