What are the Benefits of 300 Series Stainless Steel Electropolishing?

Electropolishing is an electrochemical process in which the finished part is immersed in a specially blended chemical bath, after which an electric current is run through the part. The combination of the two creates a chemical reaction on the surface of the part, removing an exceptionally thin layer of the surface metal at a uniform rate. The resulting electropolished surface is smooth, substantially brighter, and exceptionally more resistant to corrosion and contamination. 


Electropolishing brings a range of advantages to manufacturers seeking to use 300 series stainless steel in their finished products:

  • Because the material is passivated as part of the process, electropolishing boosts the already offers high levels of corrosion resistance of 300 stainless steel. Electropolishing can also produce a level of contamination resistance suitable for industries like food manufacturing and medical devices. 
  • Electropolishing can help manufacturers achieve a level of finish beyond other forms of metal protection, removing burrs and cleaning welds.
  • Electropolishing can strengthen the materials down to a microscopic level, removing microcracks, removing heat tint, and improving the metal’s fatigue life.
