Fe is the basis.
According to TU 14-1-4986-91, the chemical composition is given for steel grade 42H11M3F-SH (EP890-SH), 42H11M3F-P (EP890-P). In the finished metal, deviations from the chemical composition standards are allowed: for carbon +0,020%, for manganese and silicon ± 0.050% for each, for molybdenum +0.10%, for chromium ± 0.10%, for vanadium ± 0.030%. Cerium is introduced into the metal by calculation and chemical analysis is not determined.

Macrostructure and pollution	Macrostructure of steel to transverse the etched templeto should not be visible without using the magnifying devices of the traces of shrinkage, bubbles, cracking, slag inclusions. evaluation of the macrostructure produced by: point heterogeneity, Central porosity, phase separation and to the square of spotted segregation. Evaluation of contamination of metal non-metallic inclusions produced by: stroke oxides, oxides point, silicates fragile, silicates plastic, non-deformable silicates, sulphides. The actual results of the evaluation of macrostructure and contamination shall be recorded in the certificate.
