|Publication Date:||1 August 2019|
This specification covers an aluminum alloy in the form of die forgings 4 inches (102 mm) and under in nominal thickness at time of heat treatment, hand forgings up to 6 inches (152 mm) incl, in as forged thickness, rolled rings with wall thickness up to 3.5 inches (89 mm) incl, and stock of any size for forging or rolled rings (see 8.6).
These products have been used typically for applications requiring high strength in light-to-medium sections, but usage is not limited to such applications.
Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.
