high durability Tempered bearing steel grit for surface treatment steel shot & grit

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 Size:G10/2.5mm  G12/2.0mm  G14/1.7mm  G16/1.4mm  G18/1.2mm

                              G25/1.0mm G40/0.7mm G50/0.5mm G80/0.3mm G120/0.2mm  

Steel Grit Hardness: 

GP: Hardness: 40 - 50 HRC

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: Hardness: 50 - 60 HRC 

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: Hardness: 60 - 66 HRC

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.
