Shot peening is a process designed to extend a part’s life by improving its mechanical qualities, as well as its resistance to fatigue and corrosion.

Shot peening is a process designed to extend a part’s life. The technology of metal parts surface work hardening is widely used in the aerospace and automotive industries. 

The purpose: Shot peening is a hammering technique aimed at eliminating residual stresses on the surface of metal.

The principle: The technique consists of shooting or blasting small steel, glass or ceramic beads at the surface of the part at high speeds. 

The result: Shot peening improves the part's mechanical qualities, including resistance to fatigue and corrosion.
