Electropolishing
Electropolishing is a stainless steel polishing process based on the electrolytic removal of metal. Electropolishing achieves maximum cleanliness and passivation of stainless steel. Typically applied to surfaces with roughness factors of 20µ inch. Ra for the pharmaceutical industry.
WHAT DOES THE PROCESS INVOLVE?
The process involves removing material from metal surfaces using an acid bath.
Electropolishing levels out surface irregularities resulting from a metallographic structure altered by mechanical polishing and removes a layer of approximately half a thousandth of an inch (or more, depending on the desired finish), which typically harbors abrasive residues.
It is important to emphasize that the degree of uniformity and reflectivity will depend on the original finish of the material, and that the degree of "brightness" is not directly associated with the level of passivation.
