Microstructure and properties of the high-nitrogen Fe–Cr austenite

A new kind of corrosion-resistant austenitic Fe–Cr alloys, in which nitrogen is the only austenite stabilizing and simultaneously hardening element, is offered. Ways of obtaining the pure austenite structure are pointed out. Mechanical and some technological properties are presented. The alloys are considered as alternative materials to the usual austenitic stainless steels of 18–10 type.
