In the practice of design and design work, it is often necessary to calculate the mass of a steel circle, rod or wire of a certain length and diameter. For a circular profile, this is especially easy, given that the volume of a cylindrical piece of any material is
V = 3,14r2 h, where r is the radius of the rolling cross-section, and h is the length of the section whose mass is to be calculated. Accordingly, the desired parameter is determined from relation
M = Vρ, where ρ is the density of alloy steel of a certain grade, which is given below:
Name of alloy steel group | Example of steel grade | Density kg / m3 |
Stainless steel, structural, cryogenic | 12H18N10T | 7900 |
Low-alloy structural steel for construction | 09G2S | 7850 |
Tool steel, die | X12MF | 7700 |
Structural steel spring-spring steel | 65G | 7850 |
Tool steel, die | 5ХНМ | 7800 |
Structural alloyed steel | 30HGSA | 7850 |
nickel chromium steel | EI 418 | 8510 |
chromium-manganese nickel steel | X13H4G9 (EI100) | 8500 |
chrome steel | 1X13 (EW1) | 7750 |
chromium-nickel steel | 0Х18Н9 (ЭЯ0) | 7850 |
chromium silicone-molybdenum steel | EI107 | 7620 |
chromium-nickel-molten steel | EI69 | 8000 |
chromium-nickel-silicon steel | EI72 | 7700 |
chrome steel | 15ХА | 7740 |
chrome-alumina-molybdenum nitrided steel | 38ХМЮАА | 7650 |
chromium-manganese-silicon steel | 25HGSA | 7850 |
An approximate method for determining the mass of round bars is that according to the known tables, the weight of the running meter of the steel product is set. The method is limited by the size of the rolling profiles, and also does not take into account the difference in the densities of different grades of alloy steels. Therefore it is expedient to use it only for preliminary calculations.
