PROPRIETARY CS 304 L Heat Treatments


  • Annealing: heating to between 1010 and 1120°C for 60 minutes per 25 mm of thickness (2.5 min/mm) followed by water or air quenching. The best corrosion resistance is achieved when the final annealing temperature is above 1070°C.
    Stress relieving: can be stress relieved at 450 to 600°C for 45 minutes per 25 mm of thickness (1.5 min/mm) with little danger of sensitization. If, however, stress relieving is to be carried out above 600°C, there is a serious threat of grain boundary sensitization occurring with a concomitant loss in corrosion resistance.
