    Designation by Standards

    Mat. No. DIN EN AISI
    1.2885 X32CrMoCoV3-3-3 - H10A

    Chemical Composition (in weight %)

    C Si Mn Cr Mo Ni V W Others
    0.32 0.25 0.30 2.95 2.80 - 0.55 - 2.75 % Co

    Description
    This alloy is on of the hot work, cobalt containing tool steel.

    Applications
    Hot pressing tools exposed to severe stresses in contact with the die insert – mandrels, stamps, punching tools, dies, etc. 

    Physical properties (avarage values) at ambient temperature
    Modulus of elasticity [103 x N/mm2]: 210
    Density [g/cm3]: 7.88

    Coefficient of Linear Thermal Expansion 10-6 oC-1

    20-100oC 20-200oC 20-300oC 20-400oC 20-500oC 20-600oC 20-700oC
    12.1 12.1 12.4 12.9 13.5 14.0 14.1

    Soft Annealing
    Heat to 800-840oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 250.

    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 1020-1060oC followed by oil, air or warm bath quenching. Hardness after quenching is 49-53 HRC.

    Tempering
    Tempering temperature: See the table and diagram bellow.

    Tempering Temperature (oC) vs. Hardness (HRC)

    400oC 500oC 550oC 600oC 650oC 700oC
