| Forming: |
| The alloy has good ductility and can be formed by standard means. |
| Welding: |
| Welding by conventional methods is appropriate for this alloy. |
| Heat Treatment: |
| Alloy 52 should be annealed at 1500F followed by air cooling. Intermediate strain relieving can be performed at 1000F. |
| Forging: |
| Forging should be done at a temperature of 2150 F. |
| Cold Working: |
| The alloy is readily cold worked. Deep drawing grade should be specified for that forming operation and annealed grade for general forming. |
