About Alloy C263

Alloy C263 has high strength up to 816˚C and excellent oxidation resistance up to 982˚C. The alloy has good formability, ductility, and weldability. In the annealed condition, this alloy has excellent ductility and can easily be formed by cold working.

Gas tungsten arc welding is normally carried out using argon shielding gas. Argon +5% hydrogen has been used. Alloy C263 base metal is normally welded in the annealed condition 1148°C, rapid cool. After welding, the assembly may be aged 8 hours at 798°C, air cool. Repair welding of alloy C263 components may be done in the age-hardened condition.

Alloy C263 combines properties which make it suitable for a variety of fabricated components in both aircraft and land-based turbine applications. Contact us for more information!
