Iron-Nickel Alloy, Bars, Forgings, and Rings and Stock for Rings, Forgings, and Heading 42Fe - 37.5Ni - 14Co - 4.8 (Cb + Ta)(Nb + Ta) - 1.6Ti Solution Heat Treated, Short-Time Precipitation Hardenable Multiple Melted, High Temperature, Low Expansion
AMS5893D
This specification covers an iron-nickel alloy in the form of bars, forgings, flash-welded rings, and stock for forging, flash-welded rings, or heading.
Rationale:
AMS5893D is the result of a Five-Year Review and update of the specification. The revision updates the Title to match the Scope, adds finish requirements for larger bars (see 3.3.1.1.1), prohibits bar cut from plate (see 3.3.1.2 and 4.4.3), updates grain size requirements (see 3.5.1.1.2), adds strain rate requirements for tensile tests (see 3.5.1.2.1.1), limits alternative hardness test methods (see 3.5.1.2.2), prohibits unauthorized exceptions (see 4.4.2, 5.2.1, and 8.7), and addresses additional requirements for forging stock (see 4.4.4 and 8.8).
