Contaminant-free grinding wheels for stainless steel are composed of aluminum oxide and have less than 0.01% iron, sulfur, and chlorine to prevent rust and corrosion. Aluminum oxide is a strong, sharp, and durable abrasive that withstands heat and high speeds. Contaminant-free abrasives are often used for food processing and nuclear applications.
