PROPRIETARY UR 825 Heat Treatments

Softening and stabilizing treatments has to be done about 950 - 970°C. Cooling has to be as rapid as possible (water or rapid air cooling).
To optimize corrosion resistance behavior, and particularly to avoid any intergranular corrosion risk, softening and stabilizing treatments has to be done about 950 - 970°C (1740 - 1780°F). Cooling has to be as rapid as possible (water or rapid air cooling).
Hot forming operations can be performed between 1180 and 850°C (2150 - 1560°F). After hot forming, a stabilization heat treatment at about 950°C (1740°F) is recommended. It has to be followed by a water cooling or rapid air cooling.
