Shot peening is a special technology for the surface treatment of the blast field.

The objective of this process is to increase the resistance to fatigue of the components subjected to high tension.

Shot peening is a cold process where the component surface is shot peening with a small round shot. Each shot works like a small hammer that, in a controlled way and following well-defined parameters, generates an impact on the surface in a rounded way and under the surface, the compressed material tries to return to its initial volume thus creating compressive stresses of strong amplitude.

The superposition of impacts generates a greater distribution of the high internal compressive stress on the surface of the component. This significantly reduces the probability of breakage in the blasted material, and considerably increases the hardness of the surface. The shot used can be made of steel, stainless steel, ceramic or glass.
