Steel grit blasting is ideal for aggressive cleaning applications. Steel grit will quickly strip many types of 


surface contaminants from steel and other foundry metals. Steel grit is softer than aluminum oxide and does 


not fracture as easily, making it ideal for aircraft and aero-space applications. 


The angular nature of steel grit produces an etched surface on metal for superior adhesion of paint, epoxy, 


enamel, rubber and other coatings.

Grit Size & Hardness

Different chemistries will lead to different operating results, depending on the size and hardness of the grit. 


Since Bestar is a primary steel grit supplier, multiple chemistries of steel grit are available Steel grit 


that is formulated as a softer (40-50 HRC) metal will round off rapidly, making it ideal for quick stripping of


oxides and cleaning of molds. Harder steel grit (55-65 HRC) will maintain the angular nature of the grit to 


provide continuous cutting action.
