This specification covers a premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, flash-welded rings, and stock for forging or flash-welded rings.
Rationale:
AMS6429K is the result of a Five-Year review and update of the specification. The revision updates the Title to match the Scope and identifies material quality, updates composition reporting (see 3.1.1), addresses macrostructure requirements (see 3.4.1 and 8.8), revises hardenability (see 3.4.3), revises decarburization testing procedures (see 3.4.5.5), prohibits unauthorized exceptions (see 8.7), provides options for forging stock (see 4.4.3 and 8.8), and updates recommendations for bar and mechanical tubing (see 8.4).
