Description
Special structural steel.
Applications
Low and moderately stressed parts for vehicles, engines and machines where hard, wear resisting surface is needed. Hardness as surface hardened about 54 HRC.
Physical properties (average values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210 Density [g/cm3]: 7.80
Soft Annealing
Heat to 680-720℃, cool slowly in furnace. This will produce a maximum Brinell hardness of 241.
Normalizing
Temperature: 840-880℃.
Hardening
Harden from a temperature of 820-860℃ followed by oil or water quenching.
Tempering
Tempering temperature: 540-680℃.
