Shot Peening

shot peening

Shot peening is the process of cold working or hammering the surface of a material with steel shot at relatively high velocities. These shot particles create a series of overlapping dimples on the material’s surface which improves the fatigue strength or working life of the material.

Typical products which require shot peening are:

  • 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
