Designation by Standards
Chemical Composition (in weight %)
Low alloyed cold working tool steel.
For tough and wear resistant cutting tools (dies, punchers) for plate, woodworking tools, etc.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.94
Coefficient of Linear Thermal Expansion 10-6 oC-1
Continuous Cooling Transformation (CCT) Diagram
Time-Temperature Transformation (TTT) Diagram
Heat to 720-750oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 250.
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.
Harden from a temperature of 860-900oC followed by oil quenching. Hardness after quenching is min. 62 HRC.
Tempering temperature: 150-400oC. Average hardness after tempering is 54-62 HRC.
