Peening steel shot is used to clean and strengthen the surface of metal parts by shot blasting. Using drawing, cutting, strengthening and other processes refined, in strict accordance with the German VDFI8001/2009 and the United States SAEJ441, AMS2431 standard production, the product particle size uniform, product hardness is HV420-520, HV520-600, HV610-670, HV670-740 and HV740-800;Product particle size from 0.2mm-2.5mm， shape for cylindrical G1, G2, G3, the service life is from 3500 to 9600 cycles.

Peening steel shot material selection, well-known steel wire as raw material, its chemical composition determines it has the high quality material, has higher mechanical properties, Using the German advanced cutting technology, products in strict accordance with the German VDFI8001 SAEJ441/2009 and the United States, AMS2431 standard production, ensure that all production out balls in size, the hardness and density is uniform, at the same time reduce the other impurities in the pellet material, determine the peening steel shot less physical defects, and has more impact resistant micro organization, improve the blasting efficiency (spray).Peening steel shot has stronger toughness and is not easy to break, so it has a long life and strong impact resistance. It can achieve the shot-spraying strength in a faster and shorter time, and maintain the shot-spraying strength for a longer time. Lower consumption in the process of use, the service life is as 3-4 times than the common specifications. By selecting better shot-peening equipment, reasonable shot-peening process and using strengthened steel shot, the microstructure of cyclic strain hardening and the optimized residual compressive stress field can be obtained in the surface layer of the workpiece, and the surface roughness of the outer surface can be obtained, thus the fatigue life of the treated workpiece can be improved by 30%.

Peening steel shot can bring higher shot-blasting cleaning quality and significantly improve the cleaning efficiency. Taking the conventional spring cleaning and gear cleaning as an example, the efficiency can be increased by more than 50% by using the strengthened steel shot compared with the common high carbon steel shot.The higher service life of the strengthened(Peening) steel shot makes the dust produced will be greatly reduced. Compared with the ordinary high carbon steel shot, the dust discharge volume is reduced by more than 30% at least, which reduces the conformity of the dust removal system, prolongs the service life of the dust collector, and reduces the pollution to the environment.

 It is a real green steel shot. Mainly used in aerospace, national defense, military industry, nuclear industry, wind power industry, automobile, motorcycle, shipbuilding, transmission device, spring industry and other industries of metal surface treatment field.
