山东大鼎金属材料有限公司Bearing steel pipe is a common rolling bearing ring made of hot rolled or cold drawn seamless steel pipe. The outer diameter of the steel pipe is 25-180 3.5-20mm, and it is divided into two Bearing steel is required to have high hardness and wear resistance, as well as high performance limit, because bearing bearings bear a lot of pressure and friction at work. The uniformity of chemical composition, the content and distribution of non-metallic inclusions and the distribution of carbides in bearing steel are strictly required. It is one of the most stringent steel grades in all steel production.
