C50 / C50E is medium carbon steel with high strength steel. It is usually used in normalizing, quenching or tempering condition. C50 / C50E steel is used in the manufacture of mechanical products and spring pieces, such as forging gear, tie rod, roller, shaft, friction plate, agricultural spindle dig plowshares and heavy-duty spindle bearing,etc. C50 / C50E steel are also with high wear resistance property.
