Haynes 282 Nickel Alloy per AMS 5951 , Nickel Alloy, Corrosion and Heat-Resistant, Sheet, Strip, and Plate 57Ni - 20Cr - 10Co - 8.5Mo - 2.1Ti - 1.5Al - 0.005B Vacuum Induction and Consumable Electrode Melted, Solution Heat Treated, Precipitation Heat Treatable.
The AMS 5951 specification covers Haynes 282 corrosion and heat-resistant nickel alloy in the form of Sheet, Strip, and Plate.
Haynes 282 Sheet 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
Rene 41 alloy. Can be further aged from the annealed condition or cold reduced condition for modest gains in physical properties.
