Shot Blasting

Definition - What does Shot Blasting mean?

Shot blasting involves forcibly propelling a stream of abrasive material against a surface using high-pressure air through a nozzle.

Shot blasting is commonly used to:

  • Clean iron, steel, non-cast parts, forgings, etc.
  • Clean mechanical sheets, rods, coils, wire, etc.
  • Prepare surfaces to be painted, coated, etc.
  • Shot peening to alter mechanical properties, increasing resistance to fatigue for springs, gears, etc.

Corrosionpedia explains Shot Blasting

Shot blasting is used in almost every industry that uses metal, including:

  • Aerospace
  • Automotive
  • Construction
  • Foundry
  • Shipbuilding
  • Rail
Steel surfaces, such as aircraft carriers, ships, petroleum and water storage tanks may be shot blasted to remove rust, non-skid coatings, paint and marine growth. This may be done before these surfaces are coated (or re-coated) for corrosion resistance.
