ISO X 12 CrMoV 12 6 Heat Treatments

Quenching and tempering: 1050 ± 10°C, air cooling or oil quenching; Tempering: 650-700°C.
If a stress relief treatment is necessary, the stress relief temperature should be at least 30°C lower than the tempering temperature.
The indications of heat treatment for guidance only, except in cases where test samples are to be reference heat treated.
