This specification covers a premium aircraft-quality maraging steel in the form of bars 0.50 inch (12.7 mm) and over in nominal diameter or least distance between parallel sides, forgings, and forging stock.
Rationale:
AMS6543G results from a Five-Year Review and update of this specification that revises composition analytical methods (3.1), macrostructure (3.5.1.1.2), tensile strain rates (3.5.1.2.1.1), and quality (3.6.1), prohibits unauthorized exceptions (3.5.1.2.4, 3.8), and revises reporting (4.4.2) and marking (5.2).
