This specification covers an aircraft-quality, low-alloy steel in the form of heat-treated bars 1.50 inches (38.1 mm) and less in diameter or least distance between parallel sides.
Rationale:
AMS6346D is the result of a Five-Year review and update of the specification. The revision updates the Title to include product quality, adds composition reporting (3.1.2), incorporates requirements for alternative grain size evaluation method (3.1.1, 3.3.2, 4.2, 8.4), clarifies macrostructure (3.3.1), revises tensile test requirements including note on data source (3.3.3), revises decarburization testing requirements (3.3.4.4), incorporates requirements for periodic testing per AMS2301 (4.2, 4.4.5), clarifies testing requirements (4.2), adds note on bar stock quality (8.5) and updates the requirements for product exceptions (8.6)
