Electropolishing, which is recommended for ISO 3 and 4 (formerly Class 1 and 10) clean room laundries, enhances the surface by leveling the metal and making it smooth and shiny,
|
minimizing areas where particles, chemicals, and bacteria can be trapped. Electropolishing also removes any free iron on the surface and passivates the ss. Although electropolishing is |
expensive, it removes all the surface contaminants, passivates the surface to eliminate oxidation, and leaves a smooth surface (typically 16 RMS) that is easy to keep clean |
