Super Steel Grit

When the scouring power of shot isn’t enough, the sharp, angular structure of Super Steel Grit offers the raw cutting power to clean a wide variety of surfaces and part.

Advantages of Super Steel Grit

• 200 to 1000 times recyclable, depending on hardness, velocity, type of job and carry out losses.
• Versatile - can be used on Wheel Blast Machines and Pressure Operated Blast Systems.
• High Density and strength for fast blast rate and low dust
• Super Steel Grit is manufactured according to the International Standards SAE J444 and SAE J827

Available Sizes of Super Steel Grit:

G10	G12	G14	G16	G18	G25	G40	G50	G80	G120

	Profile
GP Super Steel Grit, (46-50HRC)	GP Super Steel Grit rounds off rapidly in use and is particularly suited for removing sand of casting and scaling oxide.
GL Super Steel Grit, (56-60HRC)	GL Super Steel Grit is harder than GP Steel Grit. It loses sharpness during operation and is suited for plate and section preparation.
GH Super Steel Grit, (60-66HRC)	GH Super Steel Grit has maximum hardness to maintain angularity during operation and provides a constant cutting (etching) action. GH Super Steel Grit is specifically designed for Air Blast Operations.
