MIL Grade L 1 Heat Treatments


  • Solutionizing, cooling, stress-relieving, and aging shall be performed uniformly on the material being processed. The quenching of tubular components shall be done vertically with the bore unobstructed, so as to permit free passage of the coolant through the bore. Aging shall be performed at a temperature of not less than 260°C, and for a sufficient time to ensure uniform response throughout the section.
