6、w and update of this specification.1. SCOPE 1.1 Form This specification covers an aluminum alloy in the form of rolled or forged rings. 1.2 Application These rings have been used typically for structural applications requiring good fusion weldability, a combination of good strength and resistance to
7、 stress-corrosion cracking, and for parts requiring good stability during machining, but usage is not limited to such applications. 1.2.1 Certain design and fabrication procedures may cause these rings to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such c
8、onditions. 1.3 Classification Rings covered by this specification are classified by type of mechanical stress relief as follows: Type 1 - Stress relieved by stretching (2219T351) Type 2 - Stress relieved by compression (2219T352) 1.3.1 Either type may be supplied, unless a specific type is ordered.
9、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
10、document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply.
