Electropolishing.
The gold standard in stainless steel surface treatment. We provide unparalleled corrosion resistance and a chemically pure finish for mission-critical components in aerospace, medical, and nuclear sectors.
Engineered for Critical Surface Performance.
Electropolishing refines the surface at a microscopic level, improving corrosion resistance, cleanability, durability and visual consistency across stainless steel and specialist alloy components.
Superior Corrosion Resistance
Removes embedded contaminants, free iron and surface imperfections to support the formation of a chromium-rich passive layer for long-term material protection.
Passive LayerPrecision Micro-Deburring
Preferentially removes microscopic peaks and burrs, smoothing complex forms and internal geometries that mechanical finishing methods cannot reliably access.
Micro FinishCleaner Hygienic Surfaces
Reduces pits and microscopic entrapment points, helping components meet the rigorous demands of medical, pharmaceutical, and high-purity environments.
CleanabilityConsistent Bright Finish
Produces a smooth, uniform and highly reflective appearance while preserving component geometry, ideal for both technical and visible applications.
Visual QualityThe Science of Surface Excellence.
A controlled electrochemical process designed to refine surface condition, improve corrosion resistance and deliver a cleaner, brighter finish for precision components.
01. The Electrolytic Bath
Components are immersed in a proprietary electrolyte solution centered on bespoke chemical formulations developed by Anopol engineers to ensure optimal surface reactivity.
02. Controlled Ion Removal
A DC current is applied, making the component the anode. This triggers precision removal of surface metallic ions, specifically targeting microscopic peaks and burrs.
03. Levelling & Passivation
As the surface levels, the process removes impurities and free iron. This leaves behind a chromium-rich surface that is chemically passive and ultra-hygienic.
04. Quality Assurance
Parts undergo careful rinsing and drying before final inspection to ensure compliance with recognized standards, including ISO 15730 and ASTM B912.
Specialist Metals Beyond Stainless Steel.
Careful selection of the process electrolyte solution allows electropolishing to be carried out on specialist metals including Titanium, Copper and Duplex materials. While stainless steel remains our primary focus, our technical expertise extends to the world's most demanding alloys.
Trusted Across Critical Industries.
Electropolishing Insights.
What materials can Anopol electropolish?
We specialise in the precision treatment of austenitic (300 series) and martensitic (400 series) stainless steels, alongside Duplex and Super Duplex alloys. Our technical facility also accommodates exotic materials including Hastelloy, Inconel, and Titanium.
How much material is removed during processing?
Dimensional changes are typically restricted to between 10 and 40 microns. This removal is uniform and meticulously controlled by our engineers to ensure your components maintain strict design tolerances.
Why choose electropolishing over mechanical methods?
Mechanical polishing can "smear" surface metal, trapping contaminants. Electropolishing removes the outer layer entirely, eliminating surface stress while creating a chromium-rich, passive surface inherently more resistant to corrosion.
Is the process compliant with international standards?
Absolutely. All Anopol electropolishing processes are conducted in accordance with major international specifications, including ISO 15730, ASTM B912, and specific aerospace requirements.
