AISI E52100- Ball bearing steel is a kind of high-carbon high chromium bearing steel with good performance and wide application. After quenching and tempering, it has a higher hardenability, high hardness heat treatment, high contact fatigue strength, good dimensional stability and corrosion resistance, has been used for rolling bearing sleeves with wall thickness of 12mm. outer diameter less than 250mm and steel balls with diameters of 25.4 – 50.8mm, or where need large loads. high wear resistance and high contact fatigue strength such as military bearing, precision spindle bearing, etc or other mechanical parts and various precision gauge cold mold.
