Physical properties (average values) at ambient temperature:
Modulus of elasticity: 210 [10³xN/mm²]
Density: 7.80g/cm³
Soft annealing:
Heat to 700-740°C, cool slowly in furnace, this will produce a maximum Brinell hardness of 220
Stress relieving:
Stress relieving to remove machining stresses should be carried out by heating to approx, 650°C, 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 770-800°C (for diameter up to 50mm), 800-850°C(for diameter up to 50-80mm) followed by water quenching
Hardness after quenching is 64-66 HRC
Tempering:
Tempering temperature: 150-250°C
Hardness after tempering is 57-63 HRC
Forging:
Hot forming temperature: 1050-850°C
