properties
Waspaloy is a hardenable nickel-based superalloy with very good strength properties at temperatures of around 980 ° C. Other features include good corrosion resistance and relative insensitivity to oxidation , making Waspaloy well suited for use in extreme environments.
The alloy has good strength at temperatures up to 760-870 ° C and good oxidation resistance in gas turbine engines up to 870 ° C. The creep rupture strength of Waspaloy is better than that of Inconel 718 at temperatures above 620–650 ° C. The short-term hot tensile strength at temperatures of up to 730 ° C exceeds that of Inconel 718.
use
Waspaloy will often appear in extreme environments. It is common in gas turbines , seals, rings, shafts, and turbine disks. The NIST -certified reference material 1243, a standard for X-ray fluorescence analysis , is made from Waspaloy.
