2021 New Style Hot Roll Seamless Steel Pipe - Bearing steel pipe high precision – Lu Detail:
Introduction
Bearing steel pipe refers to a seamless steel pipe that is hot-rolled or cold-rolled (cold drawn) for the manufacture of ordinary rolling bearing rings. The outer diameter of the steel pipe is 25-180 mm, and the wall thickness is 3.5-20 mm. There are two types of ordinary precision and higher precision. Bearing steel is the steel used to make balls, rollers and bearing rings. Bearings are subjected to great pressure and friction during work, so the bearing steel is required to have high and uniform hardness and wear resistance, as well as high elastic limit. The requirements for the uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict. It is one of the most stringent steel grades in all steel production.
