Electrolytic (as well as electrochemical) polishing is one of the best possible surface treatments for stainless steels. The principle is to remove the iron atom from the surface of the stainless steel. After removing the metal atom at the surface, the alloying elements remain largely the surface and the surface is corrosive passive. In this way, the treated product is essentially protected by the treatment against impurities on its surface, as this process significantly reduces the undesirable consequences of mechanical surface treatments. The finish is highly decorative and high-quality.
