PROPRIETARY Alloy 800HT Heat Treatments

Hot Forming: The hot-working temperature range for Alloy 800H and 800HT is 950 – 1200°C if deformation is 5 percent or greater. If the degree of hot deformation is less than 5 percent a hot working temperature range between 850 – 1050°C is recommended. If the hot working metal temperature falls below the minimum working temperature, the piece must be re-heated. The alloys should be water quenched or rapid air cooled through the temperature range of 540 – 760°C. Alloys 800H and 800HT require solution annealing after hot working to ensure optimal creep resistance and properties. Cold Forming: The alloys should be in the annealed condition prior to cold forming.
