        1. Bearing Steel

          Bearing steel, also known as high carbon chromium steel, has a carbon content Wc of about 1% and a chromium content Wcr of 0.5%-1.65%. Bearing steel is divided into six categories: high carbon chromium bearing steel, chromium-free bearing steel, carburized shaft steel, stainless bearing steel, medium and high temperature bearing steel and antimagnetic bearing steel.

          High-carbon chromium bearing steel GCr15 is the most productive bearing steel in the world. Its carbon content Wc is about 1%, and its chromium content Wcr is about 1.5%. Since its birth in 1901, the main components have remained basically unchanged for more than 100 years. With the advancement of science and technology, the research work continues, and the product quality continues to improve, accounting for more than 80% of the world's total production of bearing steel. So that if there is no special description for bearing steel, it refers to GCr15.

          Additional Information

          High contact fatigue strength.

          After heat treatment, it should have a high hardness or a hardness that can meet the performance requirements of the bearing.

          High wear resistance, low friction coefficient.

          high elastic limit.

          Good impact toughness and fracture toughness.

          Good dimensional stability.

          Good anti-rust properties.

          Good cold and hot processing properties.

          Application

          Bearing steel is a kind of steel used to manufacture balls, rollers and sleeves of rolling bearings. It can also be used to make precision measuring tools, cold punching dies, machine tool screws, such as punching dies, measuring tools, taps and precision accessories for diesel oil pumps. Bearing steel is the steel used to make balls, rollers, and bearing rings.
