Electropolishing Stainless Steel

Electropolishing Stainless Steel

  • If you are looking for a reliable electropolishing company, our line provides for electropolishing and passivation of stainless steel. Our industrial processes are battle tested, reliable, and economical. Everywhere, where the highest standards in metallic functionality and appearance exist, electropolishing is often recommended. Electropolishing also works very well on micro surfaces, without changing the form or structure of the metal. Our chemical treatments remove a thin surface layer from the main surface without any mechanical or thermal stress to the material. All of the contaminants, particles, micro tears or scratches, disruptions to internal micro structures, and local stresses are removed during our electropolishing process.
  • In every day language, in order for steel to be considered “stainless steel”, it must have a minimum of 10.5% chromium content by mass. Contrary to its name, stainless steel is not 100% stain-proof. However, it is much more resistant to corrosion, staining, and rust than traditional steel. Stainless steel exhibits a very thin passivation film on its surface, which is mostly made up of chromium oxide. In comparison to other types of steel, this protective layer in stainless steel is highly corrosion resistant. However, repeated mechanical processes or thermal exposure can damage this normally protective film over time. For this reason, passivation is often necessary. In sum, Capron’s Passivation process removes surface contamination to leave a clean finish; electropolishing extends the process even further, leaving a bright, shiny finish that extends corrosion resistance.
  • On both lines, electropolishing and passivation, our work meets the quality standards and guidelines of ASTM.
