DIN 1.8844 Heat Treatments

  • Stress relief annealed at 530-580°C, cooled in still air. The holding period is a total of 150 minutes (even with multiple anneals). For a holding time of more than 90 minutes, the lower limit of the temperature range should be aimed for.
    Heating to temperatures above the stress relieving temperature of 580°C may affect the strength properties.
