NB 16MnNiMo Heat Treatments

  • Forgings should be delivered in the heat treated state and various materials should be heat treated as follows:
    - Austenitizing at a temperature between 850°C and 900°C;
    - Water quench;
    - Tempering at temperature min. 630°C.
  • The heat treatment, should include the following process:
    - austenitizing at a temperature between 850°C and 925°C,
    - quenching by immersion in water,
    - tempering at a temperature selected so as to obtain the required properties, followed by still air cooling.
    Holding temperature for tempering shall be between 635°C and 665°C. Holding time at that temperature shall depend on the thickness of the plate, on the minimum basis of half an hour per 25 mm of thickness.
