High-strength steel partenitskaya.
Standards
Chemical composition
Fe is the basis.
According to TU 14-1-1846-76 the chemical composition is presented for steel grade 01Н17К12М5Т-ИЛ (ЭП845-ИЛ) - steels of vacuum-induction smelting with the subsequent electron-beam remelting. Estimated content of modifiers and deoxidizers: magnesium, calcium, barium, hafnium and boron is established by technological instructions of the supplier of metal and their residual content in the metal is not determined by chemical analysis. Deviations in titanium by +0.10% are allowed; by nickel by +0.30%; for silicon and manganese, provided that their sum is not more than 0.20%, for carbon by +0.0050%. A residual chromium content of up to 0.30% is allowed.
