Fe is the basis.
According to TU 14-1-5016-91 the chemical composition is given for steel grade 08H2G2FA. When melting steel in the main open-hearth furnaces and electric furnaces with acid lining, the mass fraction of phosphorus is allowed up to 0.030%. The final deoxidation is carried out by aluminum, calcium-containing deoxidizers and REM from the calculation of the production of 0.01-0.050% in finished aluminum, calcium and REM not less than 0.0010% of each. The content of aluminum, calcium and REM in steel is not controlled and is provided technologically during smelting. Deviations in chemical composition are allowed in the finished product: carbon +0.010%, silicon + 0.230 / -0.020%, manganese ± 0.25%, chromium ± 0.25%, vanadium ± 0.010%.
