HEAT TREATMENT:
· SOFT ANNEALING: Heat to 720-750°C, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
· STRESS RELIEVING:Stress relieving to remove machining stresses should be carried out by heating to approx. 650°C, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
· HARDENING:Harden from a temperature of 760-820°C, 800-840°C followed by water or oil quenching. Hardness after quenching is 64-66 HRC.
· TEMPERING: Tempering temperature: 150-250°C. See the data bellow.
