Steel Shot Blasting Media Abrasive
Steel Shot is ideal for peening applications to impart a clean, smooth finish. This dense, smooth media can be used up to 3,000 times and produces minimal dust during the blasting process.
Steel Shot Blasting Media Abrasive
Steel shot blasting abrasive is the most widely used process for cleaning, stripping and improving a metal surface. The grade or size of steel shot blasting abrasive will determine the ultimate finish achieved on the surface of the metal. The round ball shape of the steel shot produces a clean, smooth and polished surface through a peening action created by the acceleration of the shot. In a peening application, steel shot is also used to impart compressive strength to torque or load bearing metal parts such as crankshafts, engine turbine blades and heavy-duty springs.
Smaller steel shot blasting abrasive will result in a smoother and more polished surface. Larger shot will clean more aggressively but produce a rougher surface. Both air powered and wheel blast systems can be used to accelerate the steel shot onto the surface of the part. Due to the hardness and density of steel shot blasting abrasive, it can be recycled as much as 3000 times before replacement. Since steel shot does not use an abrasive process and a minimal amount of dust is created in the blasting process.

Steel Shot Blasting
Steel Shot blasting is a technique used to perfect or clean steel when specific surface finishes are required. Steel shot is utilized in pretty much every industry imaginable. These incorporate massive construction, shipbuilding, rail, and auxiliary manufacturing.
Blast cleaning with steel shot is a vital operation at various stages of primary metal production. The different varieties and the size of the steel shot give an excellent result on the metal surface. It is one of the most cost-effective since it can be recycled hundreds if not thousands of times due to its robustness and durability.
A larger steel shot blasting cleans a rougher surface thoroughly. In order to accelerate steel shot on the surface, both wheel blast and air pneumatic systems are used.
Advantages of Steel Shot Blasting
- It provides an excellent result on the metal surface finish.
- Extremely high durability
- Cost-effective & recycle ability
- Both wheel blast systems and air power can be used
- Remove surface contamination and provide a spotless surface
Steel shot blasting produces the least dust because its process is less abrasive and the media does not break down. Steel shot is used to overcome condensate strength to torque or loading metal parts such as engine turbine blades, crankshafts, and heavy-duty spring.
Steel Shot Blasting is a surface finishing method that prevents metal fatigue or cracking as well as for cleaning and surface hardening. In this method, the role of a shot is to remove rust, impurities, surface contamination, or other remains that can affect metal strength. It is environmental-friendly and a rapid, cost-effective surface finishing method that is used for cleaning, polishing metal, and other surfaces by applying a high-speed stream of round shot media.
Steel Shot Blasting also has multiple uses wherein it can remove hard scrapes, scales, and burrs, and is an excellent rust remover. Since it does effectively clean surface corrosion that may interfere with the part’s integrity, blasting becomes a reliable approach to surface treatment.
