The revision updates the Title to match the Scope and include product quality, adds composition reporting (see 3.1.2), revises macrostructure requirements (see 3.3.1 and 8.9), updates hardenability testing (see 3.3.3), revises decarburization testing requirements (see 3.3.4.4), incorporates requirements for periodic testing per AMS2301 (see 4.2.1 and 4.4.4), adds options for forging stock (see 4.4.3 and 8.9), adds note on bar stock quality (see 8.7), and updates the prohibition on product exceptions (see 8.8).
