Machining stainless steel, especially 300 and 400 series stainless steel, can leave parts with a wide array of imperfections: microburrs, microcracks, free iron, stains, heat tint, oxide scale, and other surface defects that can compromise the fit, finish, function, and durability of stainless steel parts.
Electropolishing—also known as electrochemical polishing, electrofinishing, electolytic polishing, and e polishing—eliminates stainless steel surface defects by removing a microscopically precise layer of surface material, to tolerances as low as +/-.0001″, depending on the alloy, leaving a lasting bright finish. This degree of precision and consistency, along with the ability to remove a variety of surface imperfections in one process, is why electropolishing is so often specified for critical metal parts – with 30 times more corrosion resistance than passivation.
Electropolishing also eliminates the need for mechanical metal finishing processes like hand deburring, tumbling, pickling, and cleaning.

From implantable devices to surgical instruments, electropolishing is a single-process treatment that results in biocompatible, safe and ultra clean parts.
We offer aerospace vendors and original equipment manufacturers our signature metal finishing services to increase fatigue-resistance for their metal parts, rendering them capable of withstanding the stress and corrosion that comes with long-term use.
Our strict adherence to industry standards ensures that pharmaceutical components are electropolished in accordance with ASTM B912 and ASME BPE specifications. These products are clean and smooth, corrosion resistant and contaminant free.
Corrosion resistance and microfinish improvement are essential for critical automotive parts, making electropolishing an increasingly beneficial option for automakers.
Our metal finishing services help increase corrosion resistance for these parts, and by removing the outermost layer of metal withelectropolishing the durability and longevity of these appliance components is increased.
Electropolishing materials for this industry eliminates the buildup of bacterial biofilms, as well as keeping the equipment free of contaminants like Salmonella. Electropolishing delivers the level of sanitation required by a number of regulatory agencies.
From robotics to mobile equipment, the uses of electropolishing in the hydraulics and pneumatics industry are many. By helping prevent premature part failure, electropolishing reduces downtime and increases the life cycle of these components.
Improving conductivity and performance is just one benefit electropolishing offers for electronics parts. The surface finish is improved by as much as 50%, removing imperfections from the material without material removal.
When it comes to precision metal finishing, trust is earned through consistency, quality, and a deep understanding of what’s at stake. For many industries, there is no room for error in their critical metal parts. That’s why, for over 70…
A primary reason engineers specify electropolishing to finish critical metal parts is its ability to optimize part performance with improvements to surface finish, corrosion resistance and durability.
Is electropolishing the right finishing method for your metal part?
Many machined metal parts undergo a plating or coating as the final step in production – for added durability, corrosion resistance, or to achieve a certain appearance or functionality.
