Principal Design Features
|
|
Hastelloy W is a nickel-molybdenum alloy also containing chromium and iron. It is primarily intended as a filler metal for the welding of dissimilar high temperature application alloys.
|
|
|
Applications
|
|
Used as a weld metal filler rod for the joining by welding of dissimilar alloys in the nickel-base high temperature, high strength families. The alloy is sometimes used in wrought bar form for high temperature applications.
|
|
|
Machinability
|
|
No data - the alloy is basically a weld filler metal and machines in similar fashion to metals being joined.
|
|
|
Welding
|
|
Used as a weld filler metal by all conventional welding methods.
|
|
|
Heat Treatment
|
|
The alloy is solid-solution-strengthened and, as such, is not heat treatable. Appropriate heat treatment would be that of the metals being welded.
|
|
|
Annealing
|
|
The wrought bar form of this alloy may be annealed at 2165 F for 15 minutes, followed by water quench.
