PROPRIETARY NAS 660 Heat Treatments

  • Its strength is increased through aging after solution heat treatment. Two stages of heat treatment are generally carried out, as follows:
    Solution heat treatment at 980°C, oil or water cooling
    Age hardening at 720°C/16hr, air cooling.
    After solution heat treatment, either oil or water cooling is required, though air cooling is better for thinner metal.
