What Is Stainless Steel Electropolishing?

Electropolishing Before & After

Electropolishing of Stainless Steel Before & After

Electropolishing stainless steel is a “reverse plating” process that uses an electrochemical solution to remove the outer skin of a metal part. By stripping away a uniform layer of surface material, the electropolishing process also removes embedded contaminants, heat tint and oxide scale, burrs, micro cracks, pits, and other surface imperfections that can compromise the performance and longevity of a part.

Electropolishing stainless steel significantly, especially 300 and 400 series stainless steel, improves a part’s corrosion resistance, leaving it with a lasting bright finish. Electropolishing can be performed on all varieties of stainless steel unlike passivation, and gives stainless steel parts of all kinds corrosion resistance superior to passivation alone—electropolished parts are 30x more corrosion resistant than those that are passivated. The process of dissolving a uniform layer of surface metal is more aggressive and more effective, and because it is highly controlled, it can be used to remove as little as .0002″ of surface material.
