PROPRIETARY K03 Heat Treatments

  • Annealing
    After cold deformation, a few minutes annealing at 750°C enables the structure to be restored. K03 is tempered when it is rapidly cooled from 780°C.
    Pickling
    - Nitric-Hydrofluoric acid mixture (20% HNO3 + 1% HF). Descaling pastes for weld areas.
    Passivation
    - 20-25% nitric acid bath at 20°C. Passivating pastes for weld beads
