Fe is the basis.
According to TU 14-1-818-73 the chemical composition is given for steel grade P6AM5. The presence of cobalt to 0.60% is not a sign of acceptance. The mass fraction of manganese is allowed to be 0.10% higher than indicated in the table. The mass fraction of copper should not exceed 0.25%. Deviation by the mass fraction of nitrogen ± 0.010% is allowed. Modification of steel P6AM5 by zirconium is allowed. Zirconium is introduced by calculation to 0.11-0.12% without taking into account the burn and chemical analysis is not determined. Deviations according to the chemical composition are allowed in the finished product in accordance with GOST 19265.
