Electropolishing is a process that streamlines the microscopic surface of a metal object by removing metal from the object’s surface through an electrochemical process similar to, but the reverse of, electroplating. The metal peaks or high points of the treated surface are shredded, resulting in a smooth, clean surface which has the added benefit of being easy to sterilize. Blasting your stainless steel will result in a decontaminated surface that appears smooth, but it typically leaves a coarse surface, with major disturbances still present.
International Corrosion Services offers a high-quality Electropolish treatment process in line with the ASTM B922 standard, providing superior stainless steel clean.

Electropolishing
Our electropolishing bath measures 6m x 1.5m x 1.5m making it the largest in Western Australia.
Applications
Electropolishing is the most efficient metal finishing process available. It provides thirty times the corrosion resistance compared to passivation, making it an effective process in marine environments where stainless would readily rust and deteriorate. Following electropolishing treatment, parts have a long-lasting resistance to rust, extending the life of the asset and providing a bright decorative finish. Electropolished stainless steel is also used for surgical applications as it is smooth, free of burrs, corrosion resistant and clean.
Electropolished stainless is also ideal for hospitality applications. When hydrogen is present in stainless steel it provides a suitable breeding ground for bacteria. Electropolishing is the only process that removes the presence of hydrogen from the surface and throughout stainless, protecting equipment from bacterial growth. It also removes the peaks and highpoints where bacteria can harbor, resisting contamination and moisture.

Benefits of Electropolishing Stainless Steel
- Superior physical appearance
- Enhanced mechanical properties
- Improved corrosion resistance
- A clean, smooth surface which is easier to sterilise
- Improved rust protection
- Life extension
- The ability to polish areas that are inaccessible by other polishing methods
The ASTM standard ASTM B912 recommends pickling and passivating the stainless steel to ASTM A380, a pre-treatment process for a premium stainless steel polish result, extending the life and quality of electropolished steel electropolishing. International Corrosion Services is currently the only facility in Western Australia to be able to offer this large-scale service. Learn more
