SAE AMS5663P

This specification covers a corrosion- and heat-resistant nickel alloy in the form of bars, forgings, and flash welded rings in the solution and precipitation heat treated condition. Product covered by this specification is limited to 10.00 inches (254 mm) and under in nominal diameter or maximum cross-sectional dimension between parallel sides (thickness) and nominal cross sectional area of 78.54 in2 (503 cm2). Stock may be of any size for forging or flash welded rings. AMS5663P is the result of a Five-Year Review and update of the specification. The revision prohibits unauthorized exceptions (3.5.1.6, 3.9, 4.4.2, 5.2.1.1, 8.5), updates title to match the scope, updates the description of size and size limits (1.1, 3.5.1.1, 3.5.1.3, Tables 2 and 3, 3.5.1.5.1), revises composition requirement and reporting (3.1, 3.1.1), provides for consistent heat treatment requirements between similar specs and global market (3.4.2, 4.4.1.3), clarifies transverse testing requirements (3.5.1.3.4), clarifies limitations on producing bar from plate (4.4.1.5), adds strain rate control during testing (3.5.1.3.6), adds forging stock options (4.4.3, 8.6), and allows prior revisions (8.4).
