DESCRIPTION
Haynes® Alloy 282 is an age-hardenable nickel-based superalloy that combines excellent creep strength with thermal stability, weldability, and fabricability. This new alloy has excellent creep strength in the temperature range of 1200 to 1700°F (649-927°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. Other notable properties include resistance to strain-age cracking and high-temperature oxidation.
