PROPRIETARY Timetal 679 Heat Treatments

  • Solution Heat Treatment at 900°C (1650°F) / 30 minutes / air cool + Aging heat treatment 500°C (930°F) / 24 hours / air cool.
    Faster cooling from solution heat treatment temperature by oil quenching, will increase tensile strength, while slightly decreasing ductility.
