Physical properties (average values) at ambient temperature of X20CoCrWMo10-9
Modulus of elasticity [103 x N/mm2]: 215
Density [g/cm3]: 8.08
Soft Annealing of X20CoCrWMo10-9
Heat to 760-840℃, cool slowly in furnace. Time is 4-6 hours. This will produce a maximum Brinell hardness of 320.
Stress Relieving of X20CoCrWMo10-9
Stress relieving to remove machining stresses should be carried out by heating to 600-650℃, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening of X20CoCrWMo10-9
Harden from a temperature of 1100-1150℃ followed by air, oil quenching or vacuum quenching. Hardness after quenching is about 52 HRC.

Soft Annealing
Heat to 800-840℃, cool slowly in furnace. This will produce a maximum Brinell hardness of 250.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 650℃, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening of X20CoCrWMo10-9
Harden from a temperature of 1020-1060℃ followed by oil, air or warm bath quenching. Hardness after quenching is 49-53 HRC.
Tempering of X20CoCrWMo10-9
Tempering temperature: 600-750℃, to increase hardness, temper 2 or 3 times.
