This specification covers a premium-aircraft-quality, low-alloy steel in the form of sheet, strip, and plate. AMS6439 is the result of a Five-Year Review and update of the specification. The revision prohibits unauthorized exceptions (3.7, 4.4.1, 5.1.1. 8.5), updates the composition testing (3.1), adds continuous heat treatment (3.3.3), updates decarburization methods (3.4.3), allows alternate cooling methods (3.4.4), limits tensile testing strain rate (3.4.4.1.1), and allows prior revisions (8.6).
