Designation by Standards
Chemical Composition (in weight %)
Medium alloy cold work steel, oil hardening type. Good dimesional and cutting stability; slightly lower hardenability and wear resistance, compared with highly chromium alloyed steels, but better toughness.
Cutting and punching tools for sheet thickness up to 6 mm, also for paper and plastics, roll shear blades for sheet thickness up to 6 mm, small bending and drawing tools, thread cutting tools, reamers, woodworking tools, gauges and other measuring tools, small inserts and plastic moulds.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Thermal conductivity [W/m.K]: 30.0
Electric resistivity [Ohm mm2/m]: 0.35
Specific heat capacity[J/g.K]: 0.46
Coefficient of Linear Thermal Expansion 10-6 oC-1
Continuous Cooling Transformation (CCT) Diagram
Heat to 720-750oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
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 800-830oC followed by oil quenching or warm bath quenching approx. 200oC. Hardness after quenching is 63-65 HRC.
Tempering temperature: See the data bellow.
Tempering Temperature (oC) vs. Hardness (HRC)
Hot forming temperature: 1050-850oC.
