HAYNES® 25 alloy is normaly final solution heat-treated at 2150 to 2250°F (1175 to 1230°C) for a time commensurated with section thickness. Annealing during fabrication can be performed at even lower temperatures, but a final, subsequent solution heat treatment is needed to produce optimum properties and structure. Please call Haynes International for further information.
*Based upon cold reductions taken upon 0.110-inch (2.8 mm) thick sheet. Duplicate tests.
HRC = Hardness Rockwell “C”.
