What Are Steel Shots?
Steel shots are round particles of hardened steel, typically made by atomizing molten steel and then heat-treating and quenching to obtain the desired hardness and durability. They are graded by size and hardness and are widely used in various industrial processes.

Steel shot blasting is one of the most widely adopted techniques in surface preparation industries for cleaning, stripping, and enhancing metallic surfaces. The choice of steel shot size significantly influences the final surface texture—smaller shots yield a finer, more polished finish, while larger shots provide aggressive cleaning action, resulting in a rougher texture. This process can be executed using either air-blast systems or centrifugal wheel blast machines, which propel the steel media with high velocity onto the target surface. Due to their high density and durability, steel shots can be recycled and reused hundreds of times, making them highly cost-effective. Unlike abrasive blasting that breaks down rapidly and creates high dust levels, steel shot blasting generates minimal dust, making it cleaner and environmentally favorable.
These abrasives are extensively used for cleaning and preparing metal components across industries. Applications include desanding and cleaning of foundry castings, descaling of rolled steel products, and surface preparation prior to painting or coating. Our premium-grade steel shots continue to find widespread use in automotive, aerospace, construction, mining, shipbuilding, railway, petrochemical, foundry, and general manufacturing sectors, demonstrating exceptional performance in each.
The blasting process employs hardened steel media to efficiently remove rust, mill scale, and other surface contaminants, revealing the bare metallic substrate with a bright, consistent finish. This clean surface improves the adhesion of coatings, lubricants, and paints. Additionally, shot blasting improves tooling life by eliminating abrasive contaminants that would otherwise cause premature wear on cutting or forming equipment. It often eliminates the need for additional surface treatment after fabrication. By bombarding the surface with a controlled stream of metallic shots—ranging from spherical balls to angular grit—manufacturers achieve surface roughness suitable for both functional and aesthetic enhancements.
