This specification covers two grades of a premium aircraft-quality, corrosion-resistant steel in the form of bars, wire, forgings in the solution heat treated condition, and forging stock. Product covered by this specification is limited to a nominal 6.00 inches (152.4 millimeters) and under diameter or maximum cross-sectional dimension between parallel sides (thickness), unless the product is tested in the response to H1000 condition (see 3.5.1.2 and 8.7). When product is tested in the H1000 condition, the product is limited to 8.00 inches (203.2 millimeters) and under diameter or maximum cross-sectional dimension between parallel sides (thickness). Stock for forging may be of any size.
Rationale:
AMS5617L is the result of a Five-Year Review and update of the specification. The revision updates the Title to match the Scope adding an additional reference UNS number, updates Scope adding section size limits and clarifying conditions (see 1.1), revises composition testing and reporting requirements (see 3.1 and 3.1.1), prohibits bar cut from plate (see 3.3.1.1.3 and 4.4.2), adds strain rate to tensile test requirements (see 3.5.1.2.1), changes E45 method consistent with table requirements (see 3.5.1.1.5), adds bar quality requirements (see 3.6.1.2 and 8.4), clarifies testing based on response to heat treatment (see 4.2.1), addresses forging properties (see 4.4.3 and 8.7), adds response to heat treatment to reports (see 4.4) updates the exception requirements (see 3.5.1.3 and 8.6), and adds ordering requirements based on above changes (see 8.7).
