Nickel Alloy, Corrosion- and Heat-Resistant, Bars, Forgings, Extrusions, Rings, and Stock for Forgings, Extrusions, and Rings 62Ni - 21.5Cr - 9.0Mo - 3.65Cb (Nb) Annealed
This specification covers a corrosion- and heat-resistant nickel alloy in the form of bars, forgings, extrusions, flash welded rings up to 10 inches (254 mm) in diameter, thickness, or for hexagons, least distance between parallel sides, and stock of any size for forgings, extrusions, and rings.
AMS5666K is the result of a Five-Year Review and update of the specification. The revision updates the title to match the scope, updates terminology on size (1.1, 3.3.1), revises composition reporting (3.1.1), adds condition (3.2.1), revises testing (184.108.40.206), prohibits unauthorized exceptions (220.127.116.11, 3.7, 4.4.3, 18.104.22.168, 8.6), controls strain rate during testing (22.214.171.124.1), updates definitions (8.3), adds extrusions (8.7), and allows prior revisions (8.5).
