Description
Non alloy special sructural steel.
Applications
Quenched and subsequently tempered steel for vehicle and engine components, crankshafts for vehicle construction and diesel engines, gear shafts.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Soft Annealing
Heat to 650-700oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 217.
Normalizing
Normalizing temperature: 850-880oC.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 129-200oC, 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 830-860, 820-850oC followed by oil or water quenching. Hardness after quenching is 53-59 HRC.
Tempering
Tempering temperature: 480-650oC.
Forging
Hot forming temperature: 1100-850oC.
Machinability
No data.
