Electropolish

Electropolishing is a process that removes material from the surface of the part. The removal of outer layer material from the metallic work piece creates a shiny, mirror finish resembling the polish of bright chrome car parts. Because of the removal of material, deburring occurs on burrs up to .005″; even on the most complex of parts. No distortion of the part occurs because the process is non-mechanical. Material removal also results in reduced microfinish values of up to 50%. This can be critical for parts where metal contact is important. Since electropolishing removes impurities from the surface of the part, corrosion resistance is increased, acting as a form of passivation.

We electropolish 300 series, nitronic 60, 17-4ph, duplex stainless steel parts. Depending on carbon content of the steel, we can run 400 series as well. The cosmetic appearance is substantially enhanced when the 300 series part is electropolished versus a 400 series part. This is because the chromium and nickel within the alloy are greater in the 300 series. The increased levels of chromium and nickel give the part a shimmering finish when the surface impurities are removed. Our electropolishing processes conform to ASTM B912 specifications.
