PROPRIETARY P420M HT K4 Heat Treatments

  • The stress relieving is carried out between 530 and 600 °C followed by cooling in still air. The total holding time should not exceed 150 minutes, even if several operations are carried out. With holding times of more than 90 minutes the lower limit of the temperature range should to be aimed at.
