Principal Design Features
|
|
This is an age-hardenable, high nickel content alloy, with very good thermal and electrical conductivity.
|
|
|
Applications
|
|
Typically used for electrical contact applications such as springs.
|
|
|
Machinability
|
|
May be readily machined by conventional means, although machining is best when the alloy is in the age-hardened condition.
|
|
|
Forming
|
|
Easily formed by conventional means.
|
|
|
Welding
|
|
Fusion welding is not recommended due to the composition of the alloy. Electric resistance welding may be used.
|
|
|
Heat Treatment
|
|
Solution anneal at 2000 F and water quench. This is followed by the aging treatment at 910 F for 16 hours and furnace cool.
|
|
|
Forging
|
|
Forging may be done at 2200 F to 1700 F. Note that after forging a solution anneal must be done -- see "Annealing".
|
|
|
Hot Working
|
|
Hot working may be done in the range of 2200 F to 1200 F. Note that after hot work a solution anneal must be done -- see "Annealing".
|
|
|
Cold Working
|
|
The alloy readily cold works by conventional means.
|
|
|
Annealing
|
|
Anneal at 2000 F and water quench.
|
|
|
Hardening
|
|
Hardens due to cold working and aging - see "Heat Treat". A combination of cold working and aging will produce the greatest tensile strength.
|
|
|
Other Mechanical Props
|
|
In the age-hardened heat treat condition the tensile properties are approximately 50% greater and the elongation is reduced by about 50% in comparison to the annealed values shown.
