SAE AMS 6395E:2000 pdf download Steel Sheet, Strip, and Plate 0.95Cr – 0.20Mo (0.38 – 0.43C) (SAE 41 40)
1 . SCOPE:
1 .1 Form: This specification covers an aircraft-quality, low-alloy steel in the form of sheet, strip, and plate.
1 .2 Application: These products have been used typically for heat treated parts, 0.875 inch (22.22 mm) and under in section thickness at time of heat treatment, requiring through-hardening to a minimum tensile strength of 1 80 ksi (1 241 MPa) and proportionately lower strength in heavier thicknesses, 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.
