AFCEN Z6 CNDU 20-08 M Heat Treatments

  • Parts shall be delivered in the solution heat treated condition.
    The austenizing conditions prior to solution heat treatment temperature shall be:
    - nominal temperature target during holding: above 1120°C
    - homogenisation of the part between 1010°C and 1040°C before solution heat treatment is possible.
    Maximum permissible deviation from nominal holding temperatures for the entire charge shall be ± 20°C. The parts shall be subjected to solution heat treatment by total immersion in water.
