Nimonic 263
NIMONIC®alloy 263 (UNS N07263/W. Nr. 2.4650), anair melted nickel-base alloy, was developed by Rolls-Royce (1971) Ltd. to provide a sheet material whichcould be readily fabricated and would offer improvedductility in welded assemblies to replace NIMONICalloy 80A.It was designed as sheet material to meet specificdesign criteria in terms of proof stress and creepstrength. It is now available in all standard forms.
