It is the most widely used superalloy due to its mechanical strength and creep up to 650°C. In addition, it has good corrosion resistance and ductility at cryogenic temperatures down to -250°C. Widely used in the aerospace industry as gas turbine components, it is also used in hot working tools and components used by the oil industry in sub-zero temperatures.
