Alloy 282


Alloy 282

Alloy 282 is a new, 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 new alloy has excellent creep strength in the temperature range of 1200 to 1700°F (649 to 927°C). The features of Alloy 282 alloy make it suitable for critical gas turbine applications, such as sheet fabrications, seamless and flash butt-welded rings, and cases found in compressor, combustor, and turbine sections. In augmented aircraft gas turbines, the new alloy will be useful for exhaust and nozzle components. In industrial gas turbines, the alloy is a good candidate for transition sections and other hot-gas-path components.
