UNI X 7 CrNi 18 10 Heat Treatments


  • Guideline Heat Treatment: Solutionize by heating to 1050 - 1100°C for a time sufficient to allow complete solutionizing, and quench in water or air according to the material thickness. Stress Relieving: Heat to a temperature less than or equal to 400°C for a time sufficient to stress relieve the material.
