Shot Peening; What? Why? How?

Shot peening is a crucial metal treatment process that enhances the fatigue resistance, durability, and surface hardness of components. This technique involves firing small beads at high velocity onto a material's surface, inducing compressive stress and improving mechanical properties.

What is Shot Peening?

Shot peening is a process that can increase the fatigue resistance, durability and surface hardness of a component by plastically deforming and therefore stress relieving the material surface using small beads of shot media fired at the material surface at high speed.

The high speed impact from the shot media creates multiple dimples on the surface of the material

The process uses compressed air or a centrifugal turbine to fire beads of shot media, typically steel, ceramic or glass beads, at high velocity towards the surface of the material. The impact of the media on the material surface cold works and plasticly deforms the material improving the mechanical properties.
