Fe is the basis.
According to TU 14-19-59-89 the chemical composition is given for steel grade 4ХМФч. The mass fraction of nickel, not exceeding 0.60%, is allowed. The steel is introduced by calculation for 0.001-0.10% calcium and 0.001-0.10; REM, which are not determined by chemical analysis. The residual mass fraction of copper should not exceed 0.30%. In the finished rolled products deviations are allowed according to the chemical composition in accordance with GOST 5950.

| Macrostructure and contamination | The macrostructure of rolled on the other 14-19-59-89 when checking for fractures treated or templeto selected from the finished profile should not have residues of shrinkage, delamination, cracks, bubbles, inclusions and placenow. On the surface of the rent must not be cracked, sunsets, captured, smoothed out bubbles and contamination. surface defects should be removed with gentle cleansing or cutting, the depth of which shall not exceed 5 % of the nominal diameter of the rental, counting from the actual. |
| Features of production | Hot-rolled steel on the other 14-19-59-89 supplied annealed with a hardness not to exceed 255 HB (indentation diameter not less than 3.8 mm). |
