	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.



The vacuum carburizing temperature is generally higher than that of ordinary gas carburizing. Carburizing and diffusion are often used at 920~1040 C. As shown, there are two stages: pulse ventilation, stop gas, multi-stage carburizing and diffusion. The effect is better. Vacuum carburized layer is formed faster than ordinary gas, liquid and solid carburized layer because of its high temperature, especially its clean surface and high activity. If the carburized layer needs 1 millimeters, it will take 927 hours and 1 hours at 1033 degrees Celsius, only 5 hours.

Precision steel pipe has the advantages of no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, small cold bending deformation, high flatness, no cracks and so on. It is mainly used to produce pneumatic or hydraulic components. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe
