Promise For Best Quality

BEARING STEELS

The main requirement of this category of steel is good wear resistance with anti friction properties. They generally have 1% Carbon and 1.5% Cr and on hardening and tempering achieve high hardness with excellent antifriction characteristics, fatigue strength and wear resistance.
