At Classic Electropolishing our specialty is stainless steel electropolishing. We have done electropolishing for the medical, automotive, aerospace and electronics industries. Our attention to detail and our high quality products are what set us apart from the rest.

Benefits of Stainless Steel Electropolishing

Stainless steel offers two main advantages from a manufacturing standpoint. The first advantage is that it can help remove impurities left behind during abrasive manufacturing processes. These impurities can include excess material such as burrs or small valleys. The electropolishing process helps to remove material from peaks and valleys to create a smoother serface. Secondarily, electropolishing can leave your stainless steel component looking bright and shiny. In a world of commoditized products a nice finish can help you separate from the pack. Typically the stainless steel components that we work with are from the medical industry but we work with a variety of industries.

Classic Electropolishing adheres to the stainless standard ASTM B 912-02 (2008), Passivation of Stainless Steels Using Electropolishing. Electropolishing offers cost advantages of up to 50% over traditional manual metal finishing.

Benefits of electropolishing stainless steel (from wikipedia)

  • Removes iron from the surface and enhances the chromium/ nickel content providing the most superior form of passivation for stainless steel.
  • Provides a clean and smooth surface that is easier to sterilize.
  • Polishes areas inaccessible by other polishing methods.
  • Improves the surface finish by leveling micro peaks and valleys.
  • Removes a small amount of material from the surface of the parts, also removing small burrs.
  • Can be used to reduce the size of some parts when necessary.
  • Results are seen by many as aesthetically-pleasing
