WASPALOY UNS N07001 High-temperature alloy Bar
Waspaloy is an age hardening nickel base superalloy with useful strength at temperatures up to 1400-1600°F, and good oxidation resistance in gas turbine engine atmospheres up to 1600°F. The creep-rupture strength of Waspaloy is superior to that of alloy 718 at temperatures above 1150-1200°F. Short time hot tensile strength is inferior to alloy 718 at temperatures up to 1350°F.
Welding is difficult, and best performed on material in the solution annealed condition. Limit currents and the size of the fusion zone. Rapid cooling from welding is necessary to minimize aging stresses. Copper backup bars or water cooled fixtures are desirable. After welding, the fabrication should be solution treated, using rapid heating and cooling rates through the aging range. Follow anneal by stabilization and aging treatments.
A typical heat treatment is a solution heat teat at 1825°F for 2 hours, air cool. Stabilize heat treat at 1550°F for 4 hours, air cool. Precipitation heat treat at 1400°F for 16 hours, air cool.
