PROPRIETARY Acidur 4418 Heat Treatments

  • Annealing (+ A) at 600 to 650°C, cooling in air, furnace;
    Hardening at 950 to 1050°C, cooling in polymer, oil or air;
    +QT760 - At 590 - 620°C, cooling in water, air;
    +QT900 - At 550 - 620°C, cooling in water, air;
  • Soft annealed by holding at a temperature of approximately 600°C (but not in excess of 625°C), followed by slow cooling in air. Two heat treated conditions are usually specified, namely: QT760 and QT900 (based on the minimum specified tensile strengths). Tempering temperatures should be chosen so that the range from 420 - 510 °C is rapidly traversed. Before final tempering, the steel must have already cooled throughout to below 40°C.
