UNI 1.4468 Heat Treatments

  • (+AT) Normalizing or austenitizing from 1120 to 1150ºC.
  • 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.
