FIELD: metallurgy.
SUBSTANCE: heat treatment of items is performed, which includes homogenisation, hardening, thermomagnetic treatment and multistage tempering; at that, prior to thermomagnetic treatment there additionally performed is heating and exposure so that a sigma-phase is separated.
EFFECT: increasing coercitive force of items from Fe-Cr-Co alloys.
