Bearing steel is divided into high-carbon chromium bearing steel, carburizing bearing steel, stainless bearing steel, high temperature bearing steel, medium-carbon bearing steel.

Generally, condition of delivery is hot rolled+annealing, cold drawn+annealing.




Bearing steel is a type of steel used in the field of fabricating the ball, pin roller, sleeve for antifriction bearing. and also measuring implements, cold-punching die, lead screw and precision components of diesel engine oil pump.


Product Description


The alloy is usually produced by LF /EAF /IFF /VD followed by electroslag refining (ESR) if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
