wwwwww..ssppeecciiaallmmeettaallss..ccoomm NIMONIC® alloy 263 (UNS N07263/W. Nr. 2.4650), an HHeeaatt TTrreeaattmmeenntt air melted nickel-base alloy, was developed by Rolls- Royce (1971) Ltd. to provide a sheet material which NIMONIC alloy 263 is normally given a two-stage heat- could be readily fabricated and would offer improved treatment, that is, solution treatment and age hardening ductility in welded assemblies to replace NIMONIC prior to service. This heat treatment is normally carried alloy 80A. out in air. Material is usually supplied in the solution- It was designed as sheet material to meet specific treated condition and aged by the customer as part of the design criteria in terms of proof stress and creep fabrication process. Material can however be supplied to strength. It is now available in all standard forms. any requested heat treatment condition.
