RATIONALE

AMS5715G prohibits unauthorized exceptions (3.6), revises properties (3.3.1.1), reports (4.4), and identification (5.2.1.1),

and results from a Five-Year Review and update of this specification.

1. SCOPE

1.1 Form

This specification covers a corrosion and heat-resistant nickel alloy in the form of bars, forgings, and flash welded rings

4.00 inches (101.6 mm) and under in least nominal cross section, and stock of any size for forging or flash welded rings

(see 8.5).
