Composition
30Ch13 martensitic steel grade is composed of mostly iron and chromium. According to GOST 5632−72, comprising 12−14% Cr, 0,26−0,35% C. The alloy is doped with silicon and 0.8% manganese, nickel, — up to 0.6% copper — 0.3% titanium — 0.2%, phosphorus thousandths of shares. Balance is iron. Substitute: 40X13.
