Technological properties

The value |
| Propensity to temper brittleness |
Tend not. |
| Microstructure |
Structure after annealing granular perlite; after quenching and low tempering - hidden - or fine-crystalline martensite with residual austenite and carbides. |
| Features of heat treatment |
Steel has low thermal conductivity, so the heat required exposure at an average temperature to equalize the temperature on the volume of massive parts (blanks) - stage heating. Steel treenodestyle that presupposes after hot deformation of slow cooling, followed by annealing at temperatures above the AC1 point of 30-50°C. |
| Corrosion resistance |
High corrosion resistance. |
