Soft Annealing
Heat to 800-840oC, cool slowly. This will produce a maximum Brinell hardness of 250.

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
Harden from a temperature of 940-980oC followed by oil quenching or warm bath approx. 400oC. Hardness after quenching is 64-66 HRC.

Tempering
Tempering temperature: 150-400oC.

Tempering Temperature (oC) vs. Hardness (HRC)

100oC 200oC 300oC 400oC 500oC 600oC
64 62 60 57 53 42

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.
