SAE 15-5 PH Heat Treatments

A stress relief heat treatment after precipitation heat treatment is optional. When performed, stress relief shall be accomplished by heating to 496 ± 14°C (925 ± 25°F) and soaking for at least 1 hour plus 1 hour additional for each 25 mm of thickness or fraction thereof greater than 25 mm. When load thermocouples are used, the soaking time shall be at least 1 hour.
When the ultimate tensile strength exceeds 1276 MPa, one additional aging cycle may be performed. The set temperature for the additional aging may be higher than 552°C (1025°F), but not more than 14°C (25°F) higher. The soaking time shall be not more than the original precipitation heat treatment cycle.
Homogenization Heat Treatment: heat to 2100°F ± 25 (1149°C ± 14), hold at heat for not less than 90 minutes, and cool as required.
Solution Heat Treatment: heat to 1900°F ± 25 (1038°C ± 14), hold at heat for 1 hour per inch (25 mm) of section thickness but not less than 30 minutes and cool to below 90°F (32°C) at a rate equivalent to an air cool or faster.
Precipitation Heat Treatment: heat to 1000°F ± 15 (583°C ± 8), hold at heat for 4 hours ± 15 minutes and cool in air inert gas.
