What is the process of strengthening the steel shot?

　　Steel shot has strong tolerance, moderate hardness and relatively long application life of the characteristics of the industry demand is very large, strengthen the steel shot processing it as a metal appearance of the disposal of consumables often used, with me over the past few years the continuation of the industry demand is very large. Although in the very recent years, the production of steel shot enterprises in the continuation of the development of strong, but relative to the continuation of the increase in demand is or relatively small. Therefore, the development prospect of the steel shot industry is long and short.

　　In short, shot peening is a cold disposal process, most abrasive experience can be mobilized, continue to beat parts appearance, strengthen the steel shot processing parts appearance of rust, oil, welding scars and other debris away, but also can make parts appearance crystal stretching and displacement, resulting in uniform residual pressure stress layer.

　　When the abrasive energy is similar, the abrasive appearance with sharp edges is very high, but the roughness of the workpiece appearance will be too large, stretching the paint; Strengthen the steel ball processing of semi-round, spherical abrades may be able to repair the sharp edge of the abrades into crater, the roughness value to PSPC request interval, satisfied with the adhesion of the coating request. Therefore, in field application, sharp abrasives and spherical abrasives are often mixed in one application.

　　The life of steel wire shot is 15-30% longer than that of cast steel shot, because the steel wire shot has no porosity and fluffiness, strengthening the uniformity of steel shot processing is better, steel wire shot is more used for precision parts, stainless steel wire shot is more used for stainless steel parts and aluminum castings, because the shot peening will not stain the casting, and more wear-resistant. High hardness of stainless steel shot tension for aviation engine and diesel engine blade, cylinder, connecting rod strengthening.
