Time-Temperature Transformation (TTT) Diagram

Soft Annealing
Heat to 610-850^oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 262.

Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 650^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 840-870^oC followed by oil. air or warm bath (180-220^oC) quenching. Hardness after quenching is 56 HRC.

Tempering
Tempering temperature: 150-400^oC.
