Bearing steel pipe/tube

Bearing steel pipe/tube Seamless steel pipe Features

Bearing steel is a kind of high carbon chromium bearing steel with less alloy content, good performance and the most widely used. After quenching and tempering, it has high and uniform hardness, good wear resistance and high contact fatigue performance. The steel has moderate cold working plasticity, general cutting performance, poor welding performance, great sensitivity to the formation of white spots, and temper brittleness.

After quenching and tempering, the hardness is high and uniform, wear resistance and anti-fatigue strength is high. Good thermal processing. Good machinability after spheroidizing annealing, but sensitive to white spot formation. It can be used to manufacture various bearing rings with wall thickness ≤12mm and outer diameter ≤250mm; It is also used for rolling bodies with a wide size range, such as steel balls, tapered rollers, cylindrical rollers, spherical rollers, rolling needles, etc. It is also used to manufacture molds, precision measuring tools and other mechanical parts that require high wear resistance, high elastic limit and high contact fatigue strength. Mainly used in the manufacture of internal combustion engine, electric locomotive, machine tools, tractors, steel rolling equipment, drilling machines, railway vehicles and mining machinery and other driving shaft of the ball, roller and shaft sleeve
