Quick Details
Specifications
Description
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.

Size&Application
Applications
Removal of mill scale, rust and old coatings from structural steel plates, profiles and fabrications prior to
painting. Descaling of metal forgings and heat treated items.
Deep angular etching of components prior to thermal spray metallization, galvanizing or enamelling. Etching
of mill rolls to provide consistent surface etch.
Large grits used for sand removal from large and medium sized steel and iron castings. Small grits used for
sand removal and cleaning of non ferrous castings.
