PROPRIETARY TENAX300 Heat Treatments


  • Stress relief: The procedure employs slowly heating to 500-600°C and furnace cooling until 200°C. After tooling, the stress relief must employ a temperature 50°C lower than that of the last tempering.

    Hardening: Preheat tools at 780/820°C and transfer them to another furnace hold at 1000/1040°C.
    Cooling:
    a) Salt-bath at 500/550°C.
    b) Oil
    c) Forced air.

    Tempering: Tools must be tempered immediately after hardening, as soon as they reach 60°C. It is necessary, at least, triple tempering; after each tempering, tools must be slowly cooled to room temperature. The first tempering treatment should be performed at 540°C, and the other treatments between 540-650°C, depending on the desired hardness.

    Nitriding: Nitriding must be employed after hardening and tempering, normally in temperatures between 500 and 550°C, since they are at least 50°C lower than the last tempering temperature. As the surface finishing influence the nitriding layer efficiency, it is recommended that the surface is carefully grinned and polished before the nitriding process.
