FABRICATION CHARACTERISTICS

Heat Treatment
HAYNES® 230® alloy is normally final solution heat-treated at 2250°F (1230°C) for a time commensurate with section thickness.  Solution heat-treating can be performed at temperatures as low as about 2125°F (1165°C), but resulting material properties will be altered accordingly.  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 refer to following sections and publication H-3159 for additional information.
