Nimonic 263
Material Data Sheet
Nimonic® 263 (also known as Nicrofer 5120) was developed in 1971 by Rolls-Royce Ltd. as a replacement for Nimonic® alloy 80A. It was designed to offer improved ductility in welded assemblies and to meet specific criteria in terms of proof stress and creep strength.
It is suitable both for cold forming and hot forming.
Nimonic 263® is a precipitation-hardenable nickel-chromium-cobalt alloy with the 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.
Nimonic 263® exhibits excellent intermediate temperature tensile ductility. It is not normally subject to strain age cracking problems common for gamma prime strengthened alloys. Nimonic 263® alloy is normally used for applications up to about 1650°F (900°C).
Its oxidation resistance is comparable to that for other gamma-prime-strengthened superalloys.
