Rationale: The military versions of the subject specifications specified Annealed 302 Cres per MIL-S-5059 for the plate material. The cancellation notice supeerseded Annealed 302 Cres to AMS 5516. Parts have been made with this material and are acceptable. The subject AS specifications require AMS5515 for the plate material. while this more closely matches the definition of annealed 302, AMS 5516 is also an acceptable material. Since AMS5516 is more readily available than AMS5515, it is propsed that AMS5516 be added as an option.
