Such steel
grit is made from broken cast steel shot after heat
treatment and then is heat-treated again. Excellent
material and proper heat treatment make it of high
hardness, big density and compact microscopic structure,
so it is of fast cutting speed, less abrasion and flat
cutting surface when cutting stone material. We can make
out most suitable product scheme according to
customers’ actual situation because different stone
processing enterprises have different saw equipment,
cutting speed, cutting pressure ability to cut granite,
etc. characters. We can supply customers with special
steel sand on request, such as special hardness, size,
and combination with steel shot. |

| Iron
grit is made from broken
iron shot being heat
treated, is of high
hardness, sharp angles which
make it of high-speed
spray-etching and scraping
ability. It is especially
used in metal surface
treatment which need higher
etching and scraping
requirement and is also used
surface treatment works of
outdoor sand-blasting
operation. |
