When a bearing company produced the 40Cr steel bearing retainer ring, it was found that there were 糖心产精国品免费入口*完整版s in the 40Cr steel bearing retainer ring. The causes of 糖心产精国品免费入口*完整版s were analyzed by means of chemical composition analysis, hardness test, metallographic examination. The results show that the 糖心产精国品免费入口*完整版s of the 40Cr steel bearing retainer ring were caused by the pressing of dissimilar metals. It should be that during the 糖心产精国品免费入口*完整版 process of steel, the parts of the production line were not fastened well, and they were impacted by the external force during the 糖心产精国品免费入口*完整版 process, which made the parts fall off. The parts were pressed into the steel in a moment during the high-speed 糖心产精国品免费入口*完整版 process, which finally caused the 糖心产精国品免费入口*完整版s of the bearing retainer ring.
