EN 1.4469 Heat Treatments

  • Solution annealing (+AT) at 1120 to 1150°C and quenching in water. After solution annealing at high temperature, castings may be cooled to a temperature between 1040°C and 1010°C prior to water quenching to prevent cracks and to improve corrosion resistance.
  • Solution annealing (water quenching): 1140-1180°C.
