Stainless steel pellets have moderate hardness, pure composition, and a large coverage area. Due to the lack of typical steel casting pellets such as pores and irregular shapes, their service life is longer. After treatment with stainless steel pellets, the surface of the castings is smooth and rust free, without the need for post-treatment such as acid washing, which is beneficial for environmental protection. Many people don't understand that the more uniform the particle size of the steel shot, the better?

Actually, it's not. In the field of cleaning, steel balls are thrown or sprayed onto the surface of cleaned workpieces, forming pits on the cleaned surface. Only when the pits overlap with each other can the entire surface be cleaned. The more uniform the particle size of the steel shot, the longer the time for pits to overlap with each other. But at a certain particle size mixing ratio, the steel shot plays a cleaning role, and the gap formed by the large particle size greatly shortens the shot blasting time, improves the quality of the shot surface, and enhances production efficiency.

Steel shot is widely used for descaling and rust removal of steel workpieces before coating, in which centrifugal shot blasting equipment is often used. The spherical shape and lower hardness prevent the steel shot from causing significant wear on the equipment. Because of its durability, it is a good abrasive for surface cleaning.
