While passivation is useful for removing free iron and contaminants from stainless steel, electropolishing offers a wider range of benefits:

• Electropolishing is 30x more effective than passivation for preventing corrosion and pathogen contamination, and improving cleanability for food and medical parts

• Only electropolishing can remove burrs, cracks and other surface defects with microscopic precision and Ra improvement of up to 50%

• Electropolishing can be used on far more metal alloys than passivation even when there are low levels of chromium and nickel – this includes aluminum, Nitinol and titanium
