According to TU 14-1-2682-79 the chemical composition is given for steel grade 03H13AG19 (CS36). The residual content of the elements is allowed: vanadium ≤0,10%, titanium ≤ 0.50%, other elements in accordance with GOST 5632. In the finished product, deviations in chemical composition are allowed: nitrogen -0.020%, manganese + 0.30%, carbon + 0.0050%. Calcium, cerium and boron are introduced by calculation and chemical analysis are not determined.

Technological properties
| Name |
The value |
| Weldability |
Steel is good welded by all welding processes without the need for subsequent heat treatment of welded joints. |
| Pressure treatment |
Satisfactory steel is stamped, forged. |
| Macrostructure and pollution |
The macrostructure of workpieces on the other 14-1-2682-79 (transverse treated templeto) should not be visible without using the magnifying devices of shrinkage looseness, bubbles, cracks, inclusions, twisting crust, delamination, placenow, subcortical bubbles. The defects allowed must not exceed the point of heterogeneity, Central porosity, segregated to the square of the 2 points. Contamination of metal non-metallic inclusions according to GOST 1778 shall not exceed: oxides - 3 points, sulfides - 2 points, silicates - 4 points, nitrides - 2 points. |
| Microstructure |
The contents of alpha phase in the billet on the other 14-1-2682-79 should not exceed 1.5 points. |
| Corrosion resistance |
The presence of 12-13% chromium makes the steel corrosion resistant in atmospheric conditions and malwarescanner environments. |
| Machinability |
Steel satisfactorily treated by cutting. |
| The tendency to intergranular corrosion |
Steel billets according to TU 14-1-2682-79 should not have the tendency to intergranular corrosion. |
| Viscosity |
Viscosity and ductility at temperatures below 70K plummets. |
