Reduced parameters Cast steel shot Carbon steel cut wire shot
Raw material bad physical property, more impurity, produced via centrifugal casting, air bubble generate easily ,broken easily Material has a uniform composition, less physical defects, even wear, easy control
Dust generation rate High dust generation rate, bad for the environment Low dust generation rat, friendly to the environment, the true environment-friendly steel shot
Micro-structure Add a little Austenite into Martensite, surface carbonization Deformation pearlite
Work efficiency Bad blasting effect, more time required Good blasting time, reduce the time
Shots consumption rate High consumption rate Decline 70% compared to cast steel shot
Parts surface effect Part surface staining, contaminated by dust easily Bright surface, little dust
Hardness uniformity Bad hardness uniformity, acceptance tolerance can be HRC10 Uniformly hardness, not easily crumbled
Shape uniformity Bad shape uniformity, scraps in irregular shape damage the parts’ surface Uniformly shape, not easily crumbled
Size uniformity Bad size uniformity Uniformly size, not easily crumbled |
