Description
Alloyed carbon steel.

Applications
Staticaly and dymamicaly stressed components for vehicles, engines and machines, for parts of lager cross sections, gears, crankshafts. Hardness as surface hardened is more than 54 HRC. 

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210

Soft Annealing
Heat to 650-730oC, cool slowly. This will produce a maximum Brinell hardness of 241.

Hardening
Harden from a temperature of 880-930oC followed by oil or water (conditional) quenching.

Tempering
Tempering temperature: 670-730oC.

Forging
Hot forming temperature: 1100-850oC. 

Machinability
No data.
