Black Bearing Steel Grit, Bearing Angular Steel Grit Used For Granite Cutting Detail Introduction :
Bearing Angular Steel Grit
Raw material is non casting bearing steel, it is crushed after quenching, then it is tempered. Product features with wear resistance and high impact toughness. According to different application, steel grit is devided into below 3 types:
GH: Hardness>60HRC. This type is specially developed for granite cutting with stable performance, uniform grain size and high wear resistant. It has been approved by our customers that angular steel grit are sharper, faster cutting speed than arc steel grit and sawing surface finished is flatter and smoother. GL: Hardness 53-60HRC
It is angular shape in the originals and is gradually ground round, especially applicable to removing the oxygenated surface, cleaning of metal parts and shot peening .
GP: Hardness 40-50HRC
The hardness is lowest, in the process of the abrasives blasting. Its edges are removed slowly, especially applicable to removing the oxygenated surface, cleaning of metal parts and pre-treatment.
