Steel AISI O2 (type 9G2) for a cold-working tool after different quenching, tempering, and cryogenic treatment regimes is studied. It is established that after cryogenic treatment the amount of residual austenite decreases by a factor of 4.3 compared with a quenched condition. The highest hardness 69HRCis achieved after quenching and cryogenic treatment, and in this case wear resistance is higher by a factor of 2.36 than after quenching and tempering. After cryogenic treatment there is also a reduction in friction coefficient.
