Fe is the basis.
According to TU 14-19-105-90 the chemical composition is given for steel grade 9Х6Ф2АРСТГ (ЭК15). In the finished metal, deviations from the chemical composition standards are allowed: carbon ± 0.010%, manganese ± 0.10%, vanadium ± 0.10%, nitrogen ± 0.020%, silicon ± 0.050%, chromium ± 0.050%, titanium ± 0.020%. The presence in the metal of nickel, cobalt and tungsten to 0.60% of each rejection is not. The calculated boron is established by the technological instruction and its residual content in the metal is not determined by chemical analysis. It is allowed to supply steel EC15 with the actual content of titanium in nitrogen.

Technological properties
| Name | The value |
|---|---|
| Macrostructure and contamination | In the macrostructure of steel shall not be shrinkage, delamination, cracks, bubbles, inclusions, visible without using the magnifying devices. |
| Microstructure | Steel is controlled at the carbide heterogeneity and decarburization. Actual testing results are recorded in the document about quality. To determine the depth bezoperatsionnogo layer according to the method of Sadovsky samples subjected to heat treatment regime: Annealing at 850-900 °C (exposure 2 hours) + Annealing with a temperature 1210-1250 °C (temperature of the 1st bath 160-200 °C (10 minutes exposure); temperature 2nd bath 560-580 °C (10 minutes exposure)). Carbide heterogeneity is controlled according to the method and scale No. 3 GOST 5950 on thermally treated samples in regime: Quenching from 1210-1250 °C + Vacation at 690-710 °C (exposure for 1 hour). |
| Features of heat treatment | To determine the hardness after quenching and tempering specimens subjected to quenching in oil from 1050-1080 °C + Vacation at a temperature of 170-180 °C (extract 1.5 hours), air cooling. |
