  • Q&A

    Bearing steel is used to manufacture balls, rollers and bearing rings. It can be roughly divided into four categories: High Carbon Chromium Bearing Steel (Through Hardening Bearing Steel), Carburizing Steels for Bearing (Case Hardening Bearing Steel), High Carbon Chromium Stainless Bearing Steel and High Temperature Bearing Steel.

    Bearing steel has high and uniform hardness, good wear resistance, high elastic limit and contact fatigue life, good cold and hot processing performance. Bearing steel is one of the most demanding steels in all iron and steel production. It has very strict requirements on the uniformity of chemical composition, the content and distribution of non-metallic inclusions, the distribution of carbides and so on.

    The Bearing Steel Round Bar of Shanghai BISCO International Corporation have the advantages of high purity and excellent fatigue resistance. If there is a need of this product, please feel free to contact us, we will provide you with a quotation within 24 hours since receiving your inquiry.
