This specification covers a premium aircraft-quality alloy steel in the form of bars, forgings 100 square inches in cross section and less, and forging stock of any size. AMS6527G results from a Five-Year Review and update of this specification. The revision updates the title to match the scope, prohibits unauthorized exceptions (1.1, 3.5.5.3, 3.8, 4.4.4), highlights stress corrosion susceptibility (1.2.1), updates composition reporting (3.3.1), updates macrostructure requirements (3.5.1.1, 8.7), revises decarburization testing methodology (3.5.3.4), adds pyrometry controls (3.5.5.1), reformats response to heat treatment (Table 5) revises tensile and hardness test specifications (3.5.5.1.1,3.5.5.1.2, 3.3.1), and adds optional forging stock tests and reporting (4.4.3, 8.7).
