Our bearing steel grit goes through quenching, first crushing, second crushing, first screening, second screening, third screening, tempering production procedures. Our bearing steel grit is made of chrome alloy material which are fast atomized after melting. After heat treatment,it is featured with optimum mechanical characteristics, good tenacity,high fatigue resistance,long working-life,low consumption and so on. For hardness we have GP:40-51HRC, GL:50-55HRC, GH:60-68HRC.   The bearing steel grit different with cast steel grit, it has the "CR" element, it can higher 30% life time than cast steel grit, mainly used for granite cutting and sand blasting in Shipbuilding,Container,Oil and gas pipeline,Surface pre-treatment and casting,Cold rolled steel,Construction machinery,Bridge and steel construction,Aeronautic,Stainless steel etc.
