This specification covers a premium aircraft-quality 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 in the solution heat treated condition (see 8.4), and stock of any size for forging, flash welded rings, or extrusion (see 8.8).
Rationale:
AMS5629J prohibits unauthorized exceptions (3.9, 4.4.4, 5.2.1.1), revises composition (3.1) to replace obsolete chemical analysis standards, updates bar condition (3.3.1), updates heat treatment (3.4) adds strain rate control (3.5.2.2.1.1), adds machining allowance (3.6.2, 8.7), and results from a Five-Year Review and update of this specification.
