AISI 347 Heat Treatments

  • After hot working, forgings shall be cooled to a temperature below 538°C (1000°F) prior to heat treating.
    Solution treating and quenching: austenitizing/solution heat treatment temperature 1040°C (1900°F) minimum, liquid cooling. Quenching cool below 260°C (500°F).
  • Annealing at min. 1040°C (1900°F), quenched in water or rapidly cooled by other means, at a rate sufficient to prevent reprecipitation of carbides.
