Soft Annealing
Heat to 730-780^oC, cool slowly in furnace or air.

Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 650-680^oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Hardening
Harden from a temperature of 1020-1070^oC followed by air or oil quenching. Structure is martensite.

Tempering
Tempering temperature: 720-780^oC.
