    Description
    This alloy is one of the cold work, medium air hardening type tool steels. It contains chromium and molybdenum with a relatively high (1 %) carbon content and is capable of deep hardening from air quench so as to minimize distortion.

    Applications
    Used of die shapes, slitters, cutting, stamping, injection tools and similar applications where wear resistance is important

    Time-Temperature Transformation (TTT) Diagram

    Soft Annealing
    Heat to 800-840oC, 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 650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

    Hardening
    Harden from a temperature of 930-970oC followed by air, oil, warm bath (500-550oC) quenching. Hardness after quenching is 63 HRC.

    Tempering
    Tempering temperature: 150-550oC

    Forging
    Hot forming temperature: 1050-850oC.

    Machinability
    Machinability is medium, about 85 % that of the W group of tool steels which are rated at 100% for a baseline.

    Corrosion Resistance
    Corrosion resistance of this alloy is better than that of plain carbon steels. However it will rust unless given protective treatment.

    Welding
    This is an alloy steel and thus capable of being welded. Consult the alloy supplier for welding procedures.
