1. SCOPE:
1.1 Form: This specification covers a premium aircraft-quality, maraging steel in the form of bars, forgings, mechanical tubing, flash welded rings, and stock for forging or flash welded rings.
1.2 Application:
These products have been used typically for parts, such as pressure vessels, requiring through hardening, without quenching, to a minimum yield strength of 240 ksi (1655 MPa) and where such parts may require welding during fabrication, 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.
