Alloy X is a solid-solution-strengthened superalloy that combines very good high-temperature strength with very good resistance to oxidizing environments up to about 2000ºF (1095ºC), and good carburization resistance. This alloy is one of the most widely used materials for fabrication of forged parts in gas turbine engines, and is also used in chemical and petrochemical plant, power plant and industrial heating applications. Alloy X may be cold-formed or hot-formed by various techniques, and is readily weldable be most standard methods.
