SAE AMS4311F-2019

Scope

Form This specification covers an aluminum alloy in the form of rolled or forged rings up to 6 inches (152 mm) inclusive@ in nominal thickness at the time of heat treatment@ and having an OD to wall thickness ratio of 10 or greater (see 8.6). Application These rings have been used typically for applications requiring a combination of high strength@ resistance to stress-corrosion cracking@ and good stability during machining@ but usage is not limited to such applications. Classifications Rings are classified by type of mechanical stress relief as follows: Type 1 - Stress-relieved by stretching (7075-T7351) Type 2 - Stress-relieved by compression (7075-T7352) Either type may be supplied@ unless a specific type is ordered.
