DESCRIPTION
HAYNES® 282® alloy 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 (649to 927°C), surpassing that of Waspaloy alloy, and approaching that of R-41 alloy HAYNES® 282® alloy can be further aged from the annealed condition or cold reduced condition for modest gains in physical properties.
