Here’s how electropolishing works: Metal parts are placed and secured in a special rack, then submerged into a specially blended chemical bath. An electrical current is applied to the part. The charge causes a chemical reaction that smooths the part’s surface by removing an extremely thin layer of metal at a controlled, uniform rate. The electropolishing process can be monitored and completed to meet exacting specifications for cleanliness, smoothness, and corrosion protection. Your stainless steel -- such as 300 series and 400 series stainless steel -- and other metal parts, components, and equipment need to be as perfect as possible.
