SAE AMS 6543C:2001 pdf download Steel, Bars and Forgings, Maraging 2.0Cr – 1 0Ni – 8.0Co – 1 .0Mo (0.1 0 – 0.1 4C) Double Vacuum Melted, Solution Heat Treated
1 . SCOPE:
1 .1 Form: This specification covers a premium aircraft-quality maraging steel in the form of bars 0.50 inch (1 2.7 mm) and over in nominal diameter or least distance between parallel sides, forgings, and forging stock.
1 .2 Application: 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.
2. APPLICABLE DOCUMENTS: The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been canceled and no superseding document has been specified, the last published issue of that document shall apply.
