HARDENING METHOD OF AUSTENITIC NON-MAGNETIC STEEL Russian patent published in 2010 - IPC C21D6/00 C21D8/04

Abstract RU 2405840 C1

FIELD: metallurgy.

SUBSTANCE: steel is heated to 1150-1250°C, cooled to 950-1100°C, and 30% plastic deformation at the above temperatures with further exposure in the air during 60±5 seconds and cooling in water is performed.

EFFECT: increasing yield point of austenitic steel at maintaining high level of ductility and impact strength characteristics.
