Electropolishing (Stainless Steel)
Electrochemical process for complex shapes that selectively removes surface iron to enrich chromium/nickel passivation.
Process Overview
Electropolishing has widespread applications in the finishing industry because of its simplicity and the unique advantage that it can be applied to objects of highly complex shape. Typical examples include electropolished stainless-steel drums of washing machines and stainless-steel surgical devices.
One of the standout benefits of electropolishing for stainless steel is that it electrochemically removes iron from the microscopic surface peaks and enriches the chromium and nickel content, resulting in the most superior and durable form of passivation for stainless steel.
Applications & Suitable Objects
- Surgical instruments & medical implantable devices
- Washing machine drums & consumer appliance components
- Pharmaceutical processing manifolds & clean-room hardware
- Complex shaped valves, impellers & marine hardware
Finishing Characteristics & Benefits
Superior Form of Passivation
Enriches surface chromium/nickel ratio for peak corrosion resistance.
Flawless for Complex Geometries
Penetrates intricate recesses, coils, and interior channels.
Microscopic Surface Smoothing
Removes micro-burrs and surface roughness, inhibiting bacterial adhesion.
Mirror-Clean Hygiene
Creates ultra-clean, sanitary surfaces that are easy to sterilize.
