Heat Treatment

HAYNES® 244® alloy is furnished in the annealed condition, unless otherwise specified. The alloy is usually annealed in the range of 2000-2100°F (1093-1149°C), depending upon specific requirements, followed by an air cool (or more rapid cooling) before aging. A water quench is recommended for heavy section components. Aging is performed by holding at 1400°F (760°C) for 16 hours, furnace cooling to 1200°F (649°C) and holding for 32 hours, followed by air cool.
