Electropolishing of stainless steel
Electropolishing is a process that dissolves the surface of a metal by a few microns electrochemically, using the object as the anode in a phosphate-based solution. As the surface is dissolved during the polishing process, contaminants on the surface are removed, resulting in a very clean surface. Additionally, there is no processing alteration layer caused by mechanical polishing such as buffing, and a surface with the same properties as the deep layers of the metal is obtained.

It is stainless steel electro-polishing that achieves a smooth surface.
In the electrolytic polishing solution, a product (stainless steel) is used as the anode, and direct current is applied to electrochemically dissolve its surface at the micron level. At this time, due to the characteristics of the electrolytic polishing solution, the protruding areas of the metal are preferentially dissolved, resulting in a smooth surface. By applying electrolytic polishing, the passive film that stainless steel inherently possesses becomes even more robust, enhancing its corrosion resistance.
