Description
Special structural steel.
Applications
Hot-rolled steels for quenched and tempered springs.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.80
Soft Annealing
Heat to 640-680oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 310.
Normalizing
Temperature: 850-880oC, air.
Hardening
Harden from a temperature of 840-870oC followed by oil quenching.
Tempering
Tempering temperature: 430-500oC, air.
Forging
Hot forming temperature: 1050-850oC.
Machinability
No data.
