Bearing steel pipe refers to hot rolled or cold rolled (cold drawn) seamless steel pipe used for manufacturing ordinary rolling bearing rings. The outer diameter of the steel pipe is 25-180mm, and the wall thickness is 3.5-20mm, which can be divided into two types: ordinary precision and higher precision. Bearing steel is used to make balls, rollers and bearing rings. Bearing works under great pressure and friction, so bearing steel is required to have high and uniform hardness, wear resistance and high elastic limit.
The requirements for the uniformity of chemical composition, the content and distribution of non-metallic inclusions, and the distribution of carbides of bearing steel are very strict. It is one of the most stringent steel grades in all steel production.

The A335 pipes has a high level of Chromium and Molybdenum presence in it. While Molybdenum increases the overall strength, resistance, elasticity, hardenability and overall quality, moly ensures that the material is more resistant to softening, restrains the growth of grains and lessens the chances of embrittlement. It is the single additive that is responsible for the increase in high temperature resistance and it also improves the corrosion resistance to steel.
