PROPRIETARY VCM Heat Treatments


  • Recommendations to improve tool life: Preheat slowly between 200 and 300°C before starting operation. Carry out periodic stress relief throughout the tool life.

    Stress relief: Must be performed after machining and before hardening. The relief procedure should involve slow heating to temperatures between 500 and 600°C and oven cooling to a temperature of 200°C. If applied after work, stress relief must be carried out at a temperature 50°C lower than the temperature of the last temper.

    Quenching: Heating for quenching should be between 1010 and 1030°C. It is recommended to pre-warm the tools.
    Cool in:
    a) suitable oil with agitation and heated to between 40 and 70°C.
    b) salt bath kept at 500/550°C.

    Tempering: The tools must be tempered immediately after tempering, as soon as they reach 60°C. Make at least 3 tempers and between each temper the parts must cool slowly to room temperature. Tempering temperatures should be chosen according to the desired hardness. The time of each tempering must be at least 2 hours. For pieces larger than 70 mm, the time must be calculated as a function of their dimension. Allow 1 hour for each inch of thickness.

    Nitriding: It must be carried out after quenching and tempering, as long as the nitriding temperature is at least 50°C lower than the temperature of the last tempering.
