Heat to 800-840oC, cool slowly. This will produce a maximum Brinell hardness of 250.
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.
Harden from a temperature of 940-980oC followed by oil quenching or warm bath approx. 400oC. Hardness after quenching is 64-66 HRC.
Tempering temperature: 150-400oC.
Tempering Temperature (oC) vs. Hardness (HRC)
Hot forming temperature: 1050-850oC.
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.
