Principal Design Features
|
|
Nickel 230 is one of the essentially pure nickel alloy family. The composition is controlled to close limits to ensure uniform properties from the alloy for electronic use.
|
|
|
Applications
|
|
Used for cathode plates in electron tube applications.
|
|
|
Machinability
|
|
Behaves like the other 99% nickel content alloys. It is machinable by conventional means, but "gummy" in behavior. Rigid tooling and aggressive feed rates assist in good machining.
|
|
|
Forming
|
|
Easily formed by conventional means.
|
|
|
Welding
|
|
May be welded by all of the conventional methods.
|
|
|
Heat Treatment
|
|
Does not respond to heat treatment except for annealing after cold work.
|
|
|
Forging
|
|
No data. However this is a very ductile alloy and thus is readily forgeable.
|
|
|
Hot Working
|
|
See "Forging".
|
|
|
Cold Working
|
|
Readily cold worked by conventional tooling and methods. Cold work does harden the alloy and, depending upon the amount of working, it may be necessary to anneal the finished part.
|
|
|
Annealing
|
|
Anneal at 1600 F and air cool.
|
|
|
Hardening
|
|
Hardens by cold working only.
