本规范旨在涵盖适用于强化喷丸技术的喷丸球。采购产品的完整要求应包括本文件和最新版基本规范AMS2431。符合本规范的喷丸球通常用于金属表面的超声波活化喷丸处理，以向这些表面施加压缩应力，从而提高抗疲劳和应力腐蚀开裂的能力。这些球也可用于喷丸成形过程。

This specification was issued to cover peening balls suitable for an enhanced peening technique.The complete requirements for procuring the product shall consist of this document and the latest Issue of the basic specification, AMS2431.Peening balls conforming to this specification are typically intended for use in ultrasonically activated shot peening of metal surfaces to impart compressive stresses to these surfaces thereby increasing resistance to fatigue and stress corrosion cracking. These balls can also be used in the peen forming process.
