HAYNES^® 625 alloy is normally final annealed at 1925°F (1050°C) for a time commensurate with section thickness. Annealing during fabrication can be performed at even lower temperatures, but a final subsequent anneal at 1925°F (1050°C) is usually required to produce optimum structure and properties. Please see Haynes International publication H-3159 for further information.
