Soft Annealing
Heat to 720-750^oC, 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^oC, 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 800-820^oC, 830-850^oC followed by water or oil quenching. Hardness after quenching is 64-67 HRC.

Tempering
Tempering temperature: 200-600^oC.
