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 distance between parallel sides, forgings, and forging stock. These products have been used typically for heat treated parts requiring a combination of high strength, toughness, and weldability, but usage is not limited to such applications.
