Shot Peening

Shot peening is another significant application of S330 Steel Shot. This mechanical process is used to induce compressive residual stresses on the surface of a metallic workpiece, enhancing its fatigue strength and longevity. The steel shot is blasted at the workpiece, causing plastic deformation and creating a layer of compressed metal on the surface. This layer serves as a protective shield against cracks and corrosion. The inherent durability and uniform size of the S330 Steel Shot make it an excellent choice for shot peening, as it can withstand repeated impact and ensure consistent results.

Surface Preparation

Surface preparation is another crucial application area for S330 Steel Shot. It is instrumental in treating surfaces before coating, painting, or welding. The process involves blasting the steel shot at the surface to remove rust, scale, and other contaminants, achieving a clean, roughened surface that promotes better adhesion for coatings or paints. The robust and durable nature of S330 Steel Shot means it can effectively clean large, strong structures such as ship hulls, bridges, and heavy machinery without causing damage.
