Technological properties

Name 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.
