PROPRIETARY UGI 4057 AIR Heat Treatments

  • Heat treatments are composed of two steps: austenization and tempering. Austenitization is performed in the range 950°C to 1030°C, for a dwell time of 30 min minimum. Cooling must be fast enough to avoid grain boundary precipitation that would be detrimental for toughness, but not too fast to avoid quench cracking. Oil quenching (with a moderate drasticity fluid) or air cooling can be per-formed depending on the size of treated parts.Tempering conditions may vary depending on customer’s specifications. For the QT900, the recommended tempering treatment routes are: 640°C / 4h / AC + 610°C / 4h / AC (double tempering) and 650°C / 4h / AC (single tempering).
    Semi-annealing includes:
    - austenitization at rather low temperature to form globular carbides, typically at 800°C for a dwell time of 2 hours followed by furnace cooling until 600°C and air cooling below;
    - high temperature tempering at 680-700°C for 4 hours followed by air cooling.
    Slowly heated to 850°C, then more quickly to 1150/1180°C for forging between 1180°C and 950°C. Forging must be followed by a stress relief heat treatment at 200°C or softening at between 750 and 850°C or hardening and tempering.
