Designation by Standards
Chemical Composition (in weight %)
Low alloyed cold working tool steel.
Cold work tools for grey cast iron, brass, copper, stone etc.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.80
Heat to 720-760oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 220.
Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Harden from a temperature of 770-810oC, 780-840oC followed by water or oil quenching. Hardness after quenching is approx. 66 HRC.
Tempering temperature: 150-200oC. Average hardness after tempering is 60-65 HRC.
Tempering Temperature (oC) vs. Hardness (HRC)
Hot forming temperature: 1000-800oC.
