Principal Design Features
|
|
This nickel-copper alloy, similar to Monel K500, has better machinability. It may be precipitation hardened by heat treatment for good strength.
|
|
|
Applications
|
|
The alloy is used for pump shafting, fasteners, and valve components as well as finding application for propeller shafts.
|
|
|
Machinability
|
|
This alloy is similar to Monel K500, but with improved machinability. It machines much the same as the austenitic (300 Series) stainless steels.
|
|
|
Forming
|
|
The alloy has good ductility and is readily formed by conventional methods.
|
|
|
Welding
|
|
Weldability is good by conventional means.
|
|
|
Heat Treatment
|
|
This alloy responds to a precipitation hardening heat treatment and to annealing.
|
|
|
Forging
|
|
May be forged at temperatures of 2100 F to 1850 F. Water quench after forging.
|
|
|
Hot Working
|
|
Hot work temperature range is 2100 F to 1600 F. Do not allow the product to slow cool in air, rather it should be cooled from 1450 F (or higher) by quenching.
|
|
|
Cold Working
|
|
The alloy has good ductility and may be cold worked by conventional means.
|
|
|
Annealing
|
|
Annealing is done at 1900 F and water quench.
|
|
|
Aging
|
|
Aging is done at 1100 F to 1125 F for 16 hours, followed by slow furnace cooling at a rate of 25 F per hour to 900 F. Cooling rate from 900 F is not critical.
