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.
