PROPRIETARY 3Cr12 Heat Treatments

  • Annealing: heating between 700 and 750°C for 90 minutes per 25 mm of thickness (3.5 min/mm) followed by air cooling. Controlled atmospheres are recommended in order to avoid excessive oxidation of the surface.
    Stress relieving: at 600 to 650°C for 60 minutes per 25 mm of thickness (2.5 min/mm). stress relieving after welding is not normally required. If it is necessary, temperatures between 200 and 300°C are recommended.
