ASTM A965 Heat Treatment

Forgings shall be furnished in the solution treated condition. On completion of forging operations, the forgings shall be solution annealed and quenched in water, oil, or a polymer water solution. Direct quenching after completion of forging without subsequent reheating to the temperatures prescribed in 6.2-6.5 is not permissible.
For Grades F304H, F309H, F310H, F316H, F321H, F347H, and F348H, the minimum solution annealing temperature shall be 1925°F [1050°C].
Grades FXM-11 and FXM-19 shall be solution annealed at 1950°F [1065°C].
Grade F46 shall be solution annealed in the temperature range of 2010–2140°F [1100–1170°C].
The remaining grades in Table 1 shall be solution annealed at a minimum temperature of 1900°F [1040°C].
