Abrasives are used for grinding, polishing, or cleaning hard surfaces. SSPCSP 6/NACE No. 3 calls for the use of abrasives in the methods listed. The abrasives selected for this method depend on a variety of factors. In order to select an appropriate abrasive, the type, grade, and surface condition of the steel need to be considered.
