Most stainless steel types can be successfully electropolished. Electropolishing is an electrochemical process, using relatively low voltage which provides a smoothed surface that optimizes the corrosion resistance of the substrate and provides a more uniform, cosmetic finish.
Electropolishing is generally accomplished in a solution comprised of phosphoric and sulfuric acids. The process is very effective in removing contamination and debris left from mechanical treatments or machining.
Electropolish is very effective as a form of corrosion resistance as electropolished surfaces should be fully passive. It is also effective for use on complex shapes where mechanical polishing is difficult or impossible to achieve.
- Removes machining burrs with a lower risk of entrapped surface contamination such as snagged lint, etc..
- Improves surface cleanliness compared to mechanically finished surfaces.
- Provides lower surface stress by eliminating “micro-cracks" on the surface of the material.
