Introduction


Bearing steel contains rare elements (Cr, Mo) producing a stable, refined internal structure. Bearing steel grit delivers exceptional stability and wear resistance —over 2.5 times of the service life of high-carbon cast steel shot and low-carbon cast steel grit.


High-performance grit alloyed with chromium for extended service life in heavy-duty descaling and granite cutting applications. Available in GP, GL, and GH hardness grades.
