    Description
    Cold working tool steel. It is generally supplied hardened and tempered to 880-1080 N/mm2. Higher sulphur content proviedes good machinability at relatively high hardness.Possibility of nitriding. Steel has good polishability.

    Applications
    Tools for plastics processing and moulds for pressure die casting.

    Time-Temperature Transformation (TTT) Diagram

    Soft Annealing
    Heat to 710-740oC, 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 830-880oC followed by oil or quenching or warm bath quenching 180-220oC. Hardness after quenching is 51 HRC.

    Tempering
    Tempering temperature: See the data bellow.
