Description
This alloy is on of the hot work, cobalt containing tool steel.
Applications
Hot pressing tools exposed to severe stresses in contact with the die insert – mandrels, stamps, punching tools, dies, etc.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.88
Coefficient of Linear Thermal Expansion 10-6 oC-1
| 20-100oC | 20-200oC | 20-300oC | 20-400oC | 20-500oC | 20-600oC | 20-700oC |
| 12.1 | 12.1 | 12.4 | 12.9 | 13.5 | 14.0 | 14.1 |
Soft Annealing
Heat to 800-840oC, 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 650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Harden from a temperature of 1020-1060oC followed by oil, air or warm bath quenching. Hardness after quenching is 49-53 HRC.
Tempering
Tempering temperature: See the table and diagram bellow.
Tempering Temperature (oC) vs. Hardness (HRC)
| 400oC | 500oC | 550oC | 600oC | 650oC | 700oC |
| 49 | 50 | 51 | 50 | 44 | 37 |
