Steel Grit
Model : STEEL GRIT
With high hardness, high toughness, high impact resistance, long use life, good elasticity, can be used repeatedly for a few times. And also, with good adhesion, high cleaning speed, low wear rate, not broken, bright workpieces’ surface and good sandblasting effect can be obtained.

Type A Hardness >60HRC
Applied for granite gangsaw cutting, surface treatment for cold roll and
pre-treatment of metal parts.
Type B Hardness >53-60HRC
Applied for removing corrosion surface increasing roughness to get better surface preparation for coating.
Type C Hardness >40-50HRC
Applied for cleaning metal surface, such as casting parts.
