Shot peening is a mechanical surface treatment process used to improve fatigue strength and extend the service life of metal components.
During the process, small spherical media (shots) are blasted onto the surface, creating controlled compressive stress layers. This significantly enhances resistance to fatigue, stress corrosion cracking, and mechanical failure.
Shot peening is widely used in aerospace, automotive, and heavy-duty industrial applications where parts are subjected to repeated stress and high loads.
