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

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 940-980^oC followed by oil quenching or warm bath approx. 400^oC.
Hardness after quenching is 64-66 HRC. For small parts up to thickness 30 mm.
Harden from a temperature of 960-100^oC followed by air, comompressed air quenching.
Hardness after quenching is 63-65 HRC.

Tempering
Tempering temperature: 150-400^oC.
Tempering Temperature (^oC) vs. Hardness (HRC)

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

Forging
Hot forming temperature: 1050-850^oC.

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.
