Physical properties (average values) at ambient temperature
Modulus of elasticity [103xN/mm2]: 210
Density [g/cm3]: 7.85
Thermal conductivity [W/m. K]: 35.0
Electric resistivity [Ohm mm2/m]: 0.30
Specific heat capacity [J/g. K]: 0.46
Soft Annealing
Heat to 720-750ºC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 650ºC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Harden from a temperature of 800-820ºC, 830-850ºC followed by oil or water quenching. Hardness after quenching is 64-67 HRC.
Tempering
Tempering temperature: 200-600ºC
Forging
Hot forming temperature: 1150-850ºC.

Specifications:
