Haynes˘ 282
Haynes 282 is a new alloy developed for high temperature structural applications which has excellent creep strength in the temperature range of 650 – 930 °C (1200 – 1700 °F), surpassing that of Waspalloy and Rene 41. Haynes 282 possesses a unique combination of creep strength, thermal stability, weldability and fabricability that is not found in currently available commercial alloys. Its features make it suitable for critical gas turbine applications such as combustors, turbine and exhaust sections, and nozzle components.
Available in all profile options
