Heat Treatments

  • Soft annealing: 500-700°C. Soaking time 0.5-3 h. The alloy is sensitive to tension cracking when subject to annealing. Strain hardened material should, therefore, be placed in cold oven or be stress-relieved before heating to soft annealing temperature.<br /><br />Stress-relieving: 250-300°C. Soaking time approx. 1 h.
