    Time-Temperature Transformation (TTT) Diagram

    Soft Annealing
    Heat to 710-750oC, cool slowly. This will produce a maximum Brinell hardness of 210.

    Hardening
    Harden from a temperature of 870-900oC followed by oil quenching. Hardness after quenching is 63 HRC.

    Tempering
    Tempering temperature: 130-300oC.

    Forging
    Hot forming temperature: 1050-850oC.

    Machinability
    No data.
