Calculation of the weight of bulk rolled alloy steels
In the practice of design work it is often necessary to calculate the weight of steel rounds, bars or wires of certain lengths and diameters. For a circular profile this is particularly easy to do, given that the volume of a cylindrical section of any material is: V = 3,14r2 h, where r is the radius of the rolled section, and h is the length of the section whose mass needs to be calculated. Accordingly, the mass is determined from the ratio: M = Vρ, where ρ is the density of alloy steel of a certain grade, which is given below:
Name of steel | Steel grade | Density kg/m3 |
Stainless constructional cryogenic steel | 12Х18Н10Т | 7900 |
Structural low-alloy construction | 09G2S | 7850 |
Instrumental stamping | X12MF | 7700 |
Instrumental stamping | 5XHNM | 7800 |
Structural spring-spring | 65Г | 7850 |
Structural alloyed | 30ХГСА | 7850 |
Nickel-chromium | EI 418 | 8510 |
Chromium-manganese-nickel | CH13N4G9 (EI100) | 8500 |
Chromium | 1CR13 (EZH1) | 7750 |
Chromium | 15XA | 7740 |
Chrome-nickel | 0CR18H9 (EJ0) | 7850 |
Chrome-silicon-molybdenum | ЭИ107 | 7620 |
Chrome-nickel-tungsten | EN69 | 8000 |
Chromium-nickel-silicon | EN72 | 7700 |
Nitrided chromium-aluminum-molybdenum | 38CRMUA | 7650 |
Chromium-manganese-silicon | 25CGSA | 7850 |

Tabular method
The tabular method of determining the weight of round bars is that the weight of a metre of steel products is established by known tables. The method is limited by the size of the sections of rolled steel, and does not take into account the difference in densities of different grades of alloy steels. Therefore, it is advisable to use it only for preliminary calculations.
