SAE 30321 Heat Treatments

  • Annealed: 955-1120°C, quenching in water or air (to produce full austenitic structure).
  • Sheet and strip: Hot or cold rolled, solution heat treated, and, unless solution heat treatment is performed in an atmosphere yielding a bright finish, descaled;
    Plate: Hot or cold rolled, solution heat treated, and descaled.
