Wrought HAYNES® 263 alloy is furnished in the solution heat-treated condition unless otherwise specified. The alloy is normally solution heat-treated in the range of 1900 - 2150°F (1038 - 1177°C) and rapidly cooled or water quenched for optimal properties. Following solution heat treatment, the alloy is age-hardened at 1475°F (802°C) for eight hours, and air-cooled.
