Principal Design Features
|
|
Alloy 52 is one of the glass to metal sealing alloys designed for use with a variety of soft glasses. Known for a coefficient of thermal expansion that is almost constant up to 1050F (565 C).
|
|
|
Applications
|
|
Employed in a variety of glass to metal sealing applications with soft glass and ceramics.
|
|
|
Machinability
|
|
The alloy is similar to the austenitic (300 series) stainless steels in machining behavior. Sulfur containing cutting oils should be avoided as they may contaminate the alloy. A "Free-machining" grade is available for high production runs involving machining from bar stock.
|
|
|
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.
|
|
|
Annealing
|
|
See "Heat Treat".
|
|
|
Tempering
|
|
See "Heat Treat" for strain relief anneal.
