What is the process flow of reinforced steel shot processing?

　　Shot peening is a cold treatment process. A large number of abrasive particles are mobilized by energy sources to continuously beat the surface of parts. Strengthened steel shot processing removes rust, oil stains, weld scars and other debris on the surface of parts, and can also stretch and displace the crystals on the surface of parts, forming a uniform residual compressive stress layer.

　　When the kinetic energy of abrasives is similar, the surface treatment efficiency of abrasives with sharp edges is very high, but the roughness of the workpiece surface will be too large, wasting paint; reinforced steel shot processing semicircular and spherical abrasives can repair sharp-edged abrasives into craters, reduce the roughness value to the range required by PSPC, and meet the adhesion requirements of the paint. Therefore, when used on-site, sharp abrasives and spherical abrasives are often mixed together.

　　The life of steel cut shot is 15-30% longer than that of cast steel shot, because steel cut shot has no pores and is fluffy, and the uniformity of the processing structure of steel shot is also better. Steel cut shot is mostly used for precision parts, and stainless steel cut shot is mostly used for stainless steel parts and aluminum castings, because it will not contaminate the castings after peening and is more wear-resistant. High-hardness stainless steel shot is mainly used for strengthening the blades, cylinders, and connecting rods of aviation engines and diesel engines.
