Cast Steel Shot is a commonly used metal wrokpiece processing material, steel balls are tightly organized, and has uniform size. It can improve the fatigue resistance of the workpiece. The use of cast steel shot to deal with the metal workpiece surface, has characteristics of clean speed. cast steel shot and Cast Steel Grit has appropriate hardness and good resilience, internal corner and the complex parts shape can be evenly and quickly clean up, shorten the surface treatment time. It is a good surface treatment material. Cast steel shot has wide range, it need different types raw materials and equipment. Steel shot is a high quality wear resistant material, it has moderate hardness, strong toughness, good impact resistance and has long service life. When cleaning up the workpiece, it has good rebound, fast cleaning speed, low consumption. It widely used in castings, forgings, machined parts and so on. General manufacturing, shipbuilding will use cast steel shot.
