Designation by Standards
Chemical Composition (in weight %)
Hot work, tungsten-chromium-cobalt type tool steel that exhibits excellent wear and resistance to softening at elevated temperatures.
Dies, mandrels, punchers, pressing and forging dies.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.80
Heat to 820-840oC, cool slowly in furnace, 4-6 hours. This will produce a maximum Brinell hardness of 240.
Stress relieving to remove machining stresses should be carried out by heating to 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 1130-1180oC followed by oil, air quenching or warm bath quenching approx. 500oC. Hardness after quenching is about 52 HRC.
Tempering temperature: 570-700oC, at least 2-3x.
