A new superalloy, developed by industry partner Haynes International and tested by a collaborative effort led by NETL, received American Society of Mechanical Engineers (ASME) approval for use in the next generation of power plants that will operate with enhanced efficiency and produce fewer greenhouse gas emissions. The new superalloy is well-suited for other high-temperature structural applications, especially those in aero and industrial gas turbine engines, because it possesses a unique combination of creep strength, thermal stability, weldability and fabricability not found in currently available commercial alloys. Testing for advanced power plant applications was part of a $27 million project, “Advanced UltraSupercritcial (AUSC) Component Testing,” funded by the U.S. Department of Energy.
