Fe is the basis.
According to TU 14-19-59-89 the chemical composition is given for steel grade 4ХМФч. The mass fraction of nickel, not exceeding 0.60%, is allowed. The steel is introduced by calculation for 0.001-0.10% calcium and 0.001-0.10; REM, which are not determined by chemical analysis. The residual mass fraction of copper should not exceed 0.30%. In the finished rolled products deviations are allowed according to the chemical composition in accordance with GOST 5950.
