C263
Product Information
Alloy C263 is an aluminum-titanium age hardening nickel base superalloy welding wire. 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 2100°F, rapid cool). After welding, the assembly may be aged 8 hours at 1470°F, air cool. Repair welding of alloy C263 components may be done in the age hardened condition.
