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.

Compared with solid steel such as round steel, seamless steel tube has the same bending and torsion strength and light weight. It is an economical steel. It is widely used in the manufacture of structural mechanical parts such as oil drill pipe, automobile transmission shaft, bicycle frame, steel scaffolding for construction. The use of seamless steel pipe to manufacture ring parts can process, save materials and processing time, such as rolling bearing rings, Jack sleeves and so on. Steel pipes are also indispensable materials for various conventional weapons, such as pipes, guns and so on. According to the shape of the section area, the steel pipe can be divided into circular pipes and special-shaped pipes. Because the circumference is equal and the circular area is large, the circular tube can transport more fluid. In addition, the ring section under the action of internal and external radial pressure, the force is more uniform, so most of the steel pipes are circular.
