Haynes 282 Alloy Sheet(UNS N07208)
Haynes 282 alloy sheet (UNS N07208) is a wrought, gamma-prime-strengthened superalloy developed for high-temperature structural applications, especially those in aero and industrial gas turbine engines. It possesses a unique combination of creep strength, thermal stability, weldability, and fabricability not found in currently available commercial alloys. The excellent creep strength in the temperature range of 1200 to 1700°F (649 to 927°C) surpasses that of Waspaloy alloy and approaches R-41 alloy without sacrificing weldability.

Heat Treatment
Haynes 282 alloy sheet is provided in the solution-annealed condition, in which it is readily formable. The typical solution-annealing temperature is in the range of 2050 to 2100°F (1121 to 1149°C). After component fabrication, an age-hardening treatment is required to put the alloy into the high-strength condition. The standard two-step treatment includes 1850°F (1010°C) / 2 hours / AC (air cool) + 1450°F (788°C) / 8 hours / AC, but alternative heat treatments are available to optimize properties for specific performance requirements or for manufacturability.
NOTE: The heat treatment for Advanced Ultra-Supercritical (A-USC), Supercritical CO2, and Other ASME Boiler Code Applications is different from the standard heat treatment.
Application
- Sheet fabrications
- Rings
- Cases found in compressors
- Combustion and turbine sections
- Engines for aircraft
- The transition sections and other hot-gas-path components in land-based gas turbines.
