Description
Structural alloyed steel.
Applications
Statically and dynamically stressed components for vehicles, engines and machines – axles, turbine components, chains, forgings, etc.
Physical properties (average values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210 Density [g/cm3]: 7.86
Soft Annealing
Heat to 680-720℃, cool slowly. This will produce a maximum Brinell hardness of 212.
Noramlizing
Temperature: 840-900℃.
Hardening
Harden from a temperature of 840-870, 850-880℃ followed by water or oil quenching.
Tempering
Tempering temperature: 540-680℃.
