Description / Abstract:

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 peening metal surfaces to impart compressive stresses to these surfaces thereby increasing resistance to fatigue and stress-corrosion cracking. Generally, peening balls, because they are available in much larger sizes than cast steel or cut wire shot, are used where very high intensities are required to produce a very deep compressive layer. Peening balls are also frequently used in the peen forming process.
