Steel Shots S-550

Steel shots with a size of S-550 represent a specific classification within the abrasive blasting industry, where the “S” stands for spherical and “550” denotes the average particle diameter in micrometers. S-550 steel shots are characterized by their fine granularity, typically ranging from 0.3 to 0.6 millimeters. These small, uniform spheres are widely used in abrasive blasting processes to clean, prepare, or peen surfaces in various industrial applications. The S-550 size offers versatility, allowing for effective removal of rust, scale, and contaminants from surfaces while producing a consistent and controlled surface profile. This particular grade of steel shots is well-suited for applications requiring precision and efficiency, contributing to the overall quality and durability of finished products in industries such as manufacturing, construction, and metal fabrication.
