Physical properties (average values) at ambient temperature:
Modulus of elasticity [10³ x N/mm²]: 215
Density [g/cm³]: 7.84
Thermal conductivity [W/m.K]: 36.0
Electric resistivity [Ohm mm²/m]: 0.30
Specific heat capacity [J/g.K]: 0.46

Soft annealing:
Heat to 650-700℃, 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 650℃, 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 830-870℃followed by oil quenching. Hardness after quenching is 58 HRC
Air: Harden from a temperature of 830-900℃followed by oil quenching. Hardness after quenching is 56 HRC

Forging:
Hot forming temperature: 1050-850℃

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
