    Description
    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.

    Applications
    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.

    Continuous Cooling Transformation (CCT) Diagram

    Soft Annealing
    Heat to 720-750oC, 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. 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 800-830oC followed by oil quenching or warm bath quenching approx. 200oC. Hardness after quenching is 63-65 HRC.

    Tempering
    Tempering temperature: See the data bellow.
