Continuous Cooling Transformation (CCT) Diagram
Soft Annealing
Heat to 650-700oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 248.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Oil: Harden from a temperature of 830-870oC followed by oil quenching. Hardness after quenching is 58 HRC.
Air: Harden from a temperature of 830-900oC followed by air quenching. Hardness after quenching is 56 HRC.
Tempering

Forging
Hot forming temperature: 1050-850oC.
Machinability
The machinability rating of D3 is roughly 25 % that of free machining carbon steel 1018. Due to its abrasion resistant nature, machining in the hardened condition should be limited to finish grinding.
