SAE AMS5934C

This specification covers an extra high toughness, corrosion-resistant steel in the form of bars, wire, forgings, flash-welded rings, and extrusions up to 12 inches (305 mm) in nominal diameter or least distance between parallel sides (thickness) in the solution heat-treated condition and stock of any size for forging, flash-welded rings, or extrusion. AMS5934C is the result of a Five-Year Review and update of the specification. The revision prohibits unauthorized exceptions and clarifies those limitations (see 1.1, 3.5.2.2.1, 3.8, 4.4.4, 5.2.1, and 8.8), moves material types to Scope, updates composition testing and reporting (see 3.1 and 3.1.1), updates finish requirements for bar (see 3.1.1), adds heat-treatment controls (3.4), adds strain rate control for tensile testing (see 3.5.2.2.1), updates tensile and fracture toughness testing and invalidity requirements (see 3.5.2.2.2 and 3.5.2.2.3), adds quality requirements for bar product (see 3.6.2 and 8.6), adds requirements for testing of stock (see 4.2.1.5), addresses additional forging properties (see 4.4.7 and 8.9), clarifies condition (see 8.5), allows the use of prior revisions (see 8.7), and adds material type to ordering information (see 8.9)
