100Cr6 ball and roller bearing steels is specified in standard DIN 17230. It has a higher hardenability, high hardness heat treatment, high contact fatigue strength, good dimensional stability and corrosion resistance. In the manufacture of ball bearings, it is used for military bearing, aero-engine bearing, precision instrument, precision spindle bearing, etc., can also be used for bear application with large loads. high wear resistance, elastic limit, high contact fatigue strength of other mechanical parts and various precision gauge cold mould.
