  • Mat.No. 1.2662/DIN X30WCrCoV9-3

Hot work, tungsten-chromium-cobalt type tool steel that exhibits excellent wear and resistance to softening at elevated temperatures.

Designation by Standards

Mat. No.DINENAISI
1.2662X30WCrCoV9-3--


Chemical Composition (in weight %)

CSiMnCrMoNiVWOthers
0.300.230.302.35-0.258.50-Co: 2.05


Applications

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

Soft Annealing
Heat to 820-840oC, cool slowly in furnace, 4-6 hours. This will produce a maximum Brinell hardness of 240.

Stress Relieving
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.

Hardening
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
Tempering temperature: 570-700oC, at least 2-3x.
