Physical properties (averagevalues) at ambient temperature
Modulus of elasticity [10³xN/mm²]: 210
Density [g/cm³]: 7.94
Soft annealing
Heat to 720-750℃, cool slowly in furnace
This will produce a maximum Brinell hardness of 250
Stress relieving
Stress relieving to remove machining stresses should be carried out by heating to approx 650℃, holding for 1-2 hours at heat, followed by air cooling
This operation is performed to reduce distortion during heat treatment
Hardening
Harden froma temperature of 860 to 900℃, followed by oil quenching. Hardness after quenching is min 62 HRC
Tempering
Tempering temperature: 150 to 400℃
Forging
Hot forming temperature: 1050 to 850℃
