Steel shot is a type of spherical particle steel shot made from special materials and subjected to special heat treatment. It is widely used for descaling and rust removal of steel workpieces before painting, and centrifugal shot blasting equipment is often used in this case. The spherical shape and lower hardness prevent the steel shot from causing significant wear on the equipment.

Steel grit is an abrasive made from processed scrap steel of high carbon steel or alloy steel. It is mainly used for cleaning, spraying, rust removal, and strengthening of metal surfaces. The raw material of steel grit is scrap steel of high carbon steel or alloy steel. After treatment, its surface roughness can reach 25-150um, which increases the contact surface of the metal surface, improves the surface adhesion of the coating, and has significant economic benefits for refining the metal surface and strengthening the metal structure.
