Title
Titanium Alloy, Bars, Wire, and Rings, 6.0Al - 2.0Sn - 4.0Zr - 2.0Mo - 0.08Si, Solution and Precipitation Heat Treated
Scope
This specification covers a titanium alloy in the form of bars, wire, flash welded rings 3.00 inches (76.2 mm) and under in nominal diameter or least distance between parallel sides and 16 square inches (103 cm2) and under in cross-sectional area and stock of any size for flash welded rings.
Rationale
AMS4975K results from an update of this specification to restrict material to the sizes of the mechanical property tables (1.1), to require vacuum in the first consumable electrode melt (3.2), requires agreement on mechanical property values for material outside specification ranges (3.5.1.1.4 and 8.4), adds AS6279 (3.8) and revises the report paragraph (4.4).
