Nimonic C263
Description:
Nimonic C-263 (UNS N07263 / W.Nr. 2.4650) is a precipitation-hardenable nickel-chromium-cobalt alloy with an addition of molybdenum for solid-solution strengthening. It has high strength and corrosion resistance along with good formability and high-temperature ductility in welded structures. The alloy is especially suitable for sheet applications. Used in gas turbines for rings, casings, and various sheet fabrications.
Features:
Good formability
High temperature ductility in welded structures
Applications:
Nimonic C-263 is mainly used in gas turbine hot section components.
