Cr-Mo alloyed through hardening steel with high tempering resistance.
Intermediate rolls for cluster mills, trimming dies, hot cutting shears.Â
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103Â x N/mm2]: 210Â
Density [g/cm3]: 7.81
Heat to 800-840oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 250.
Stress relieving to remove machining stresses should be carried out by heating to 600-650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Harden from a temperature of 980-1020oC followed by oil quenching or warm bath quenching. Hardness after quenching is 61-63 HRC.
Hot forming temperature: 1100-850oC.Â
