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. |
