How difficult is high-end bearing steel to make

Bearing steel, as the name implies, is the raw material used to make bearings. Small bearings seem inconspicuous, but they are regarded as "the joints of high-end equipment". High-speed railways, large aircraft, submarines, warships and other "national heavy equipment" are inseparable form it.

So how difficult is it to make high-end bearing steel? This can be seen from the special working environment of the bearing. First of all, high-end bearing steel must withstand strong extrusion. It is not enough to withstand strong extrusion. High-end bearing steel also has to withstand the friction, ultra-high temperature and centrifugal force generated during high-speed rotation. Bearings in special working environments have special requirements, such as low temperature resistance, corrosion resistance and antimagnetic properties. In a word, the working environment of bearing is severe and complex, and the quality of bearing steel is extremely demanding.
