Description
Low alloyed cold work steel/" target="_blank" class="keylink">tool steel, wear resistant, for hardening in water.
Applications
Dies and tools for cold and hot forging, upsetting, deep drawing, one-part nuts, stamps.
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
| 20-100�C | 20-200�C | 20-300�C | 20-400�C | 20-500�C | 20-600�C | 20-700�C |

Continuous Cooling Transformation (CCT) Diagram
Soft Annealing
Heat to 720-760�C, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 650�C, 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 800-880, 840-950�C followed by water or oil quenching. Hardness after quenching is 64 HRC.
Tempering
Tempering temperature: 200-350�C (quenching in water), 180-300�C (quenching in oil). Average hardness after tempering is 56-62 HRC.
Tempering Temperature (�C) vs. Hardness (HRC)
