What is Shot Peening?

Shot peening is the process of accelerating small, rounded particles (shot) at the surface of a component. The shot is propelled using air or discharged by centrifugal force from an impeller wheel.

When the shot particles strike a component’s surface, they cause the surface to deform plastically, with hammerhead like impressions into the surface. As a result, it increases the fatigue life of springs and other components.

One of the reasons for this increased life is due to compressive residual stresses imparted on the surface of the component, where the operational stresses are at a maximum.

Residual Stresses Due to Shot Peening in Springs

What is Typically Shot Peened?

While our service focuses on springs, we do shot peen many other components. Typical components include:

  • Aerospace components
  • Automotive components
  • Components for the oil and gas industry
  • Medical implants
  • Seal rings
  • Springs

We have to ability to shot peen anything up to 200mm in length. Then, depending on the size of the target component (and the residual stresses required), we can shot peen using different media types, including glass and steel.
