What is shot peening?

Shot peening is the process of cold working or hammering the surface of a material with small spheres of steel, ceramic or glass media pneumatically propelled at relatively high velocities. These shot particles create a series of overlapping dimples on the material's surface which put the upper layers of the material into compression, and help to prevent fatigue failure in the material.

Shot peening improves the fatigue strength or working life for many components, including:

  • transmission gears, axles, universal joints, and drive shafts
  • connecting rods and crankshafts
  • pistons, cylinder heads and blocks
  • turbine engine disks, blades and shafts
  • aircraft wing skins, stringers and chords
  • landing gears
  • fillets
  • wheels
  • valves
  • springs
