According to TU 108.11.934-87, the chemical composition is given for steel grade 10Х2М1ФБ-ВД.
According to TU 14-1-3119-81 for steel grade 10X2M1FB, deviations in chemical composition are allowed: for carbon -0.010%, for molybdenum ± 0.050%, for vanadium ± 0.050%. The content of impurities of non-ferrous metals (tin, arsenic, lead, zinc, antimony, bismuth) should not exceed the 1 st point of a ten-point scale of spectral analysis. The content of residual elements in steel should be in accordance with GOST 5632.
