Heat treatment
| Annealed | Stress-Relieved |
|---|---|
| The soft annealing should be performed at temperatures of 700 to 900°C (1,292 to 1,652°F), preferably at about 825°C (1,517°F). | Stress-relief annealing at about 550 to 650°C (1,022 to 1,202°F) should then occur, in order to prevent stress corrosion cracking. |
