GOST 801-78 0.95-1.05 ≤0.02 ≤0.027 0.15-0.3 0.35-0.5 0.15-0.3 ≤0.3 Rest ≤0.25
Fe is the basis.
According to GOST 801-78, the total content of Ni + Cu≤ 0.50%. In steel, obtained by the method of electroslag remelting, the mass fraction of sulfur should not exceed 0.01%, and phosphorus 0.025%. When steel is smelted in acid open-hearth furnaces, the mass fraction of copper is allowed up to 0.30%, while maintaining the norm of the total share of copper and nickel is not more than 0.050%.
