Product Description

Steel grit Description

Steel Grit is an angular metallic abrasive produced by crushing bearing steel. Steel Grit is used for descaling,

coating and corrosion removal, and surface etching. The angular particle shape provides a fast cleaning rate

and an angular surface profile.

Steel Grit is tempered to three different hardnesses. The hardest material, GH, is designed for use exclusively

in air blasting equipment,stone cutting. The two softer materials, GL and GP, may also be used in centrifugal

wheel blast equipment.

Steel Grit Product Technology

Steel Grit Hardness:

GP steel grit : External form is round and shaped with steel water, owns fine elasticity and the strength of

fatigue resistance as a result of fine heat treatment, applied in all aspects, special hardness steel shot

applied in strengthening treatment.

GL steel grit : Although harder than GP steel grit, GL also loses its sharp edges during shot blasting and is

particularly suited to descaling and surface preparation applications.

GH steel grit : Having maximum hardness, GH always remains angular in its operating mix. These abrasives

are particularly effective in surface treatment processes and produce a uniform, etched finish, GH angular

grit should only be used in wheel machines where working requirements take precedence over cost price

considerations .For use mainly with compressed air blasting equipment.
