5、014-06 Superseding AMS5518L Steel, Corrosion Resistant, Sheet and Strip 18Cr - 8Ni Cold Rolled, 150 ksi (1034 MPa) Tensile Strength (Composition similar to UNS S30100) RATIONALE AMS5518M revises Scope (1.1.1), Properties (3.3.1.1), Reports (4.4), and is a Five Year Review and update of this specific

6、ation. 1. SCOPE 1.1 Form This specification covers a corrosion-resistant steel in the form of sheet and strip. 1.1.1 This specification covers products 0.005 inch (0.13 mm) and over in nominal thickness (See 8.6). 1.2 Application These products have been used typically for parts requiring strength a

7、nd moderate forming or bending, but usage is not limited to such applications. 1.2.1 Mechanical properties specified herein are obtained by cold working (strain hardening) and not by heat treatment. Therefore, the cold-worked product should not be heated to a temperature which adversely affects the

8、mechanical properties or corrosion resistance before, during, or after fabrication. 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 revisi

9、on of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply. 2.1 SAE Publications Available from SAE International, 400 Commonwealth Drive, Warren
