Shot Peening - Metal fatigue occurs during cyclic loading via tensile stress, which can cause a crack to start in highly stressed areas. Shot peening mitigates this by imparting a high magnitude, residual compressive stress at the surface in potential failure areas.
What is the purpose of shot peening? Learn how it improves fatigue life, prevents cracks, and strengthens metal components for durability.
In surface treatment processes, terms like shot peening and shot blasting are often used interchangeably—but in reality, they serve completely different

With the notable exception of laser peening, peening is normally a cold work process tending to expand the surface of the cold metal, thus inducing compressive stresses or relieving tensile stresses already present.
Peening is a metalworking process that strengthens metal surfaces by hitting them repeatedly with small, controlled impacts. Each impact creates a tiny dent, plastically deforming the surface layer and locking in compressive stress that resists cracking and fatigue.
Peening is a mechanical metalworking process designed to modify and enhance the surface properties of a material. This technique involves subjecting the material surface to repeated, controlled impacts to induce beneficial changes in its outermost layer.
