6.Soft AnnealingHeat to 710-850oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 223.7.Stress RelievingStress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.8.HardeningHarden from a temperature of 780-820oC, 800-840oC followed by water or oil quenching. Hardness after quenching is 64-66, 64-66 HRC.9.TemperingTempering temperature: 100-400oC.
