Description
Low alloyed cold work steel/" target="_blank" class="keylink">tool steel.
Applications
Dies, impact resistant tools.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.80
Coefficient of Linear Thermal Expansion 10-6 oC-1
| 20-100oC | 20-200oC | 20-300oC | 20-400oC | 20-500oC | 20-600oC | 20-700oC |
| 8.9 | 10.4 | 11.4 | 12.9 | 12.5 | 13.4 | 14.0 |
Soft Annealing
Heat to 700-740oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 220.
Stress Relieving
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.
Hardening
Harden from a temperature of 770-800oC (for diameter up to 50 mm), 800-850oC (for diameter of 50-80 mm) followed by water quenching. Hardness after quenching is 64-66 HRC.
Tempering
Tempering temperature: 150-250oC. Hardness after tempering is 57-63 HRC.
Tempering Temperature (oC) vs. Hardness (HRC)
| 100oC | 200oC | 300oC | 400oC | 500oC |
| 66 | 60.5 | 54.5 | 48 | 40.5 |
Tempering Diagram
Forging
Hot forming temperature: 1050-850oC.
Machinability
No data.
