Haynes® Alloy 282
UNS N07208
Applications
Air and land based turbines, airplane exhaust nozzles as well as high temperature automotive gaskets and seals
Description
Haynes® Alloy 282 is an age-hardenable nickel based superalloy that combines excellent creep strength with thermal stability, weldability, and fabricability. The new alloy has excellent creep strength in the temperature range of 1200 to 1700°F (649 to 927°C), surpassing that of Waspaloy alloy, and approaching that of R-41 alloy Haynes® Alloy 282 can be further aged from the annealed condition or cold reduced condition for modest gains in physical properties.
