Stainless steel grit is an angular, high-hardness, corrosion-resistant metallic abrasive. It is preferred especially for the surface cleaning and roughening of delicate metals such as stainless steel, aluminium, zamak and brass. Because it contains no iron, it creates no risk of oxidation on the surface and preserves its aesthetic appearance.
