(888) 868-2900 | Power and grid components operate in some of the harshest service conditions in manufacturing—corrosive atmospheres, thermal cycling, high pressure, outdoor weathering, and contamination-sensitive fluid systems. A single corroded fitting, contaminated valve, or fatigued connector can cascade into outages, downtime, or safety events.
Conventional machining leaves behind microburrs, free iron, embedded particles, and surface stress risers that accelerate corrosion and fatigue failure. Electropolishing removes the most damaged surface layer in a single electrochemical step, producing a smooth, passive, ultra-clean finish that resists corrosion and contamination while extending component service life.
Able Electropolishing has been the world’s largest electropolishing specialist since 1954, processing millions of critical metal parts annually. Our 50,000 sq. ft. Chicago facility runs 24/5 with 22 production lines and 13 robotic systems serving manufacturers in utility, power generation, and advanced energy.
Electropolishing enhances the performance, reliability, and service life of critical infrastructure components operating in the most demanding environments, from substation hardware to nuclear plant piping to next-generation hydrogen and SMR systems.

Distributed EnergyElectropolishing is an electrochemical process that removes a microscopically precise layer of surface material—typically 0.0002" to 0.001"—that eliminates the most contaminated and stress-laden surface zone left by machining or fabrication. The result is a chromium-enriched passive surface with measurably superior corrosion resistance, cleanliness, and fatigue life.
Removes micro-burrs and contaminants to create a passive, chromium-enriched surface—up to 30× more corrosion resistant than passivation alone.
Eliminates free iron, embedded particles, heat tint, and machining compounds, all of which are critical for fluid system hardware, hydrogen service, and nuclear applications.

Able electropolishes virtually any metal component used in utility, power generation, or advanced energy systems — including switchgear and enclosures, bus hardware and connectors, valve bodies and trim, manifolds and process piping, heat exchanger tubes and headers, pump shafts and impellers, instrument hardware, fasteners, and precision components for SMR, hydrogen, and energy-storage applications. If it’s stainless, nickel-alloy, titanium, copper-alloy, or specialty material, we likely process it.
Yes — independent ASTM salt-spray testing has demonstrated up to 30× greater corrosion resistance for electropolished surfaces compared to passivation alone. Electropolishing removes the damaged, contaminated outer surface layer and creates a chromium-enriched passive film, whereas passivation only re-passivates the existing surface. For outdoor utility hardware, plant fluid systems, and advanced energy applications, the corrosion-margin difference is significant.
Yes. Electropolishing reaches internal passages, bores, and complex geometries that mechanical polishing cannot — that’s one of its core advantages for fluid system hardware. We routinely process intricate manifold bodies, valve internals, fittings, and machined components where surface finish on internal surfaces matters as much as external finish.
