Corrosion and mechanical properties of austenitic chromium-nickel and chromium-manganese steels are studied after cold plastic deformation accompanied by formation of martensite and after aging. A steel for the production of membranes and casings of high-pulse-pressure gas sensors is chosen and modes for hardening the steel to obtain the combination of properties required for the production are determined. The inverse transformation of strain martensite into austenite is studied and a combined treatment involving a γ ↔ α transformation and elevating the strength properties at preserved austenitic state is suggested.
