PROPRIETARY Z-Wear PM Tool Steel Heat Treatments


  • Annealing: Heat uniformly in a protective atmosphere (or vacuum) to 870°C and soak for 2h. Slow cool 15°C/1h until 540°C. Parts can then be cooled in air or furnace as desired.
    Stress relieving (soft): Heat uniformly to 595 - 700°C, soak for 2h, and cool in air or furnace.
    Hardening: Vacuum, salt, or protective atmosphere methods are generally used. Care must be taken to prevent decarburization.
    Preheat: Heat to 810 - 845°C until temperature is equalized. Additional preheat steps including 620 - 650°C and at 930 - 955°C are suggested when using pogrammed control during vacuum processing.
    Austenitizing: Temperatures in the range of 1010 - 1120°C are commonly used with the specific temperature and soak time determined by the hardness required.
    Quenching: Methods include use of high pressure gas (minimum 4 bar preferred), salt bath, or oil. Quench rate from the hardening temperature range down to 700°C is critical to the development of optimum structure and properties. Part temperature can then be equalized at 540 - 595°C after which cooling can continue to below 66°C or “hand warm”.
    Tempering: Tempering should be performed immediately after quenching. Temperatures in the range of 540 - 595°C are generally used depending on the hardness required. Heat uniformly to the selected temperature and soak for 2h. Double tempering is absolutely necessary while triple tempering is recommended when hardening at 1093°C and over.”
    Stress relieving (hard): Heat to 15°C less than the temperature of the last temper and soak for 1h.
