ABS AB/4C Heat Treatments


  • Forgings are to be normalized and tempered or double normalized and tempered.
    Cooling prior to heat treatment: After forging and before reheating for heat treatment, the forgings are allowed to cool in a manner to prevent injury and to accomplish transformation.
    Normalizing: The forgings are to be reheated to and held at the proper temperature above the transformation range for a sufficient time to effect the desired transformation and then withdrawn from the furnace and allowed to cool in air. Water sprays and air blasts may be specially approved for use to achieve more rapid cooling. The faster cooling rates are to be agreed to by the purchaser.
    Tempering: The forgings are to be reheated to and held at the proper temperature, which will be below the transformation range, and are then to be cooled under suitable conditions to 315°C (600°F) or lower. The tempering temperature is not to be less than 550°C (1022°F).
    Retreatment: The manufacturer may re-heat treat the forging, but not more than three additional times.
