Electropolishing of stainless steel is the most common use of the process. Although nearly any metal will work, the most commonly electropolished metals are 300- and 400-series stainless steel. Parts made from 400-series stainless steel  have the advantage of increased hardness and strength but the trade-off is increased susceptibility to corrosion. By electropolishing stainless steel, engineers can use 400-series SS and still provide protection from corrosion.  

Electropolishing is an electrochemical finishing process that removes a thin layer of material from a metal part, typically stainless steel or similar alloys. The process

A Shiny Finish

Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing, is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.

Used In Many Industries

Due to its ease of operation and its usefulness in polishing irregularly-shaped objects, electropolishing has become a common process in the production of semiconductors.

As electropolishing can also be used to sterilize workpieces, the process plays an essential role in the food, medical, and pharmaceutical industries
