steel grit
Steel Grit is an angular metallic abrasive produced by crushing cast steel shot. 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, HG, is designed for use exclusively in air blasting equipment. The two softer materials, LG and SG, may also be used in centrifugal wheel blast equipment.

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.
