SAE AMS2590

This specification covers procedures and requirements for peening of metal parts with portable, bonded-shot, rotary flap assemblies in accordance with AS2592. The principles of rotary flap peening are similar to conventional shot peening, except conversion of arc height values using the magnetic Almen test strip holder is required for intensity determination.

The process is used for local repeening of blemished areas, straightening and reshaping of parts, and for cosmetic surface restoration of peened parts but usage is not restricted to these applications. Use of rotary flap peening requires customer approval when used to replace manual or automated shot peening.
