Alloy C263
UNS N07263
Description
Alloy C263 is a precipitation-hardenable nickel-chromium-cobalt alloy which is designed to have excellent fabrication characteristics in the annealed condition but also very good aged strength properties. The alloy has good formability, ductility, weldability, high strength up to 816 °C and excellent oxidation resistance up to 982 °C. It is resistant to strain age cracking problems, which is common for other gamma prime strengthened alloys. The combined properties make it suitable for applications up to about 1650 °F (900 °C) and a variety of fabricated components in both aircraft and land-based turbine applications.
