What is Electropolishing?
Electropolishing is a precise electrochemical process used to polish, passivate, and deburr stainless steel. Unlike mechanical polishing, it removes a thin, controlled layer of metal from the surface, resulting in a bright, ultra-clean, and corrosion-resistant finish.
It’s the gold standard for achieving a smooth, hygienic, and aesthetically superior surface — particularly on intricate or hard-to-reach parts.
Key Benefits
- Superior Corrosion Resistance: Enhances chromium-to-iron ratio for better protection in harsh environments.
- Ultra-Smooth Finish: Reduces surface roughness and eliminates microscopic burrs and contaminants.
- Hygienic & Easy to Clean: Ideal for food processing, medical, and pharmaceutical applications.
- Improved Aesthetic Appeal: Delivers a bright, reflective, uniform surface finish.
- Removes Embedded Contaminants: Cleans welds and internal surfaces where mechanical polishing can’t reach.
- Extended Component Lifespan: Reduces fatigue points and stress risers from surface imperfections.
Technical Specifications
- Material compatibility: 300-series stainless steel (304, 316, etc.)
- Surface roughness (Ra): Can reduce down to < 0.2 μm, depending on part condition
- Max part size: [Insert size capacity if applicable, e.g. 1200mm x 800mm x 800mm]
- Bath chemistry: Typically phosphoric and sulfuric acid-based electrolytes
- Surface improvement: Removes 5–40 microns of material depending on process parameters

Certifications & Compliance
- Meets standards for:
- AS 1554.6 (for stainless steel fabrication and finishing)
- ASTM B912 (Standard for electropolishing stainless)
- ISO 9001 quality assurance (if your company is certified)
- Compliant with food-grade and medical equipment surface finish requirements
FAQs
What types of stainless steel can be electropolished?
Most commonly 304 and 316 stainless steel. Other grades may be suitable upon consultation.
Is electropolishing better than mechanical polishing?
Yes — especially for complex geometries, weld cleanup, and corrosion resistance. Electropolishing removes a uniform layer from all surfaces, including crevices and internal areas.
Is it safe for food or pharmaceutical use?
Absolutely. Electropolished surfaces are smoother and easier to sterilize, making them ideal for sanitary applications.
How long does the process take?
Turnaround depends on size and quantity, but standard lead times are 3–5 business days. Rush jobs may be available upon request.
