This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock. AMS6423J results from a Five-Year Review and update of this specification that revises analytical methods (3.1), macrostructure (3.3.1.1, 3.3.1.2), hardenability (3.3.3), decarburization (3.3.4.5), quality (3.4.2), prohibits unauthorized exceptions (3.6, 4.4.4, 5.2.1, 8.5), and allows prior revisions (8.7).
