5、perseding AMS7733C Steel Wire, Copper Clad, Round 99Fe - 0.45Mn (0.13C max) Annealed RATIONALE AMS7733D is designated as stabilized by AMS Committee E because it is deemed to represent technology that is not expected change in the future. STABILIZED NOTICE This document has been declared “Stabilized
6、“ by the AMS Committee E, Carbon and Low Alloy Steels, and will not be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability of technical requirements. Newer technology may exist. 1. SCOPE 1.1 Form This specification covers a low-carbon
7、steel in the form of round wire clad with phosphorus-deoxidized copper. 1.2 Application This wire has been used typically for electronic components requiring essentially soft magnetic properties but usage is not limited to such applications. 2. APPLICABLE DOCUMENTS The issue of the following documen
8、ts 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 cancelled and no superseding document ha
9、s been specified, the last published issue of that document shall apply. 2.1 SAE Publications Available from SAE International, 400 Commonwealth Drive, Warrendale, PA 15096-0001, Tel: 877-606-7323 (inside USA and Canada) or 724-776-4970 (outside USA), www.sae.org.
