    Description
    This alloy is on of the cold work, oil hardening type tool steels.

    Applications
    Planing machine blades, tap drills, machine blades for cutting paper, paperboard and tobacco.

    Physical properties (avarage values) at ambient temperature
    Modulus of elasticity [103 x N/mm2]: Approx. 210
    Density [g/cm3]: 7.80

    Coefficient of Linear Thermal Expansion 10-6 oC-1

     

    20-100oC 20-200oC 20-300oC 20-400oC 20-500oC
    11.0 12.5 13.3 13.8 14.1

     

    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 780-820oC, 800-860oC followed by water or oil quenching. Hardness after quenching is min. 64-65 HRC.

    Tempering
    Tempering temperature: 150-300oC.

    Forging
    Hot forming temperature: 1050-850oC.

    Machinability
    No data.

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