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:
Type A: Hardness>*0HRC
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.
Type B: Hardness>****0HRC
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
