Аннотация

Chromium corrosion-resistant steels alloyed with nitrogen are studied by experiment. It is shown that depending on chemical composition and production parameters the steel’s structure may be martensitic with a minimum residual austenite content, martensitic with a higher residual austenite content, or threephase consisting of martensite, residual austenite, and ferrite. The possibility is demonstrated of residual austenite transformation into martensite during cooling after tempering at 400°C, which leads to an increase in steel hardness and correspondingly strength.
