(773) 277-1600 | The marine environment is one of the most corrosive on earth. Seawater chloride concentrations, salt spray, marine biological fouling, galvanic corrosion from dissimilar metals, and the relentless mechanical stress of wave loading combine to degrade metal surfaces faster than almost any other service environment.
Able Electropolishing works with manufacturers of components for U.S. Navy and commercial naval vessels, offshore oil and gas platforms, commercial shipping and cargo vessels, luxury and performance yachts, and marine renewable energy installations. Our electropolishing process removes micro-crevices where chloride attack initiates, creates a dense Cr₂O₃ passive layer that resists seawater corrosion, and eliminates micro-burrs that trap marine fouling organisms.
Compared to passivation alone, electropolishing is 30 times more effective for improving corrosion resistance — critical when components must perform in continuous seawater immersion, splash zone, or marine atmospheric service for years without maintenance access.
Send us your marine component for a free evaluation. We’ll electropolish it at no cost so you can see the Able difference before committing to production quantities.
Seawater contains up to 35,000 ppm chloride — enough to cause catastrophic pitting in standard stainless steel within months. Electropolishing removes micro-crevices where Cl⁻ attack initiates and elevates the Cr:Fe ratio to create a passive layer that dramatically resists seawater pitting and crevice corrosion.
U.S. Navy specifications demand absolute corrosion resistance and surface cleanliness on submarine and surface combatant components. Electropolishing meets these demanding military requirements with process certification and ITAR-compliant documentation.
Marine structural components experience constant wave-induced cyclic loading. Electropolishing removes machining stress risers that initiate fatigue cracks — extending the service life of high-cycle marine hardware including propeller shafts, rigging hardware, and structural fasteners.
The splash zone — where components alternate between immersion and atmospheric exposure — is the most corrosive marine environment. Electropolishing’s dense passive layer resists this aggressive cyclic wet-dry salt spray attack better than any other surface treatment.
Passivation alone provides thin, uneven oxide protection inadequate for marine service. Electropolishing is 30× more effective — creating a dense, uniform Cr₂O₃ barrier that stands up to seawater immersion, salt spray, and marine atmospheric corrosion over the full component service life.
Continuous immersion in 35,000 ppm chloride seawater — causes catastrophic pitting and crevice corrosion in unprotected stainless steel within months of service.
Marine atmospheric salt spray attacks metal surfaces around the clock — splash zones and topside hardware face constant wet-dry salt cycling that dramatically accelerates corrosion.
Dissimilar metal contacts in seawater create galvanic cells that rapidly attack anodic metals — electropolishing’s passive layer reduces galvanic corrosion susceptibility at bimetallic junctions.
Electropolishing meets U.S. Navy corrosion control requirements for submarine and surface ship components — process certification and ITAR-compliant documentation provided.
Electropolished components dramatically outperform passivated equivalents in ASTM B117 salt spray testing — available to verify performance on your specific alloy and application.
Able is ITAR registered — qualified to process components for U.S. Navy, Coast Guard, and defense marine applications under military specifications.
Propeller shafts, stern tubes, and cutlass bearing housings electropolished to resist seawater corrosion, improve fatigue life, and reduce friction in continuous seawater immersion service.
Fire main piping, cooling water valves, seawater ballast system components, and overboard fittings — electropolished for maximum chloride resistance in continuous seawater service.
Cleats, chainplates, turnbuckles, shackles, and standing rigging hardware electropolished for improved salt spray resistance, fatigue life, and appearance on commercial and pleasure vessels.
Pressure hull penetrations, seawater system hardware, and topside components for submarines and surface combatants — electropolished to Navy corrosion control standards with ITAR-compliant documentation.
High-strength mooring hardware, anchor chain swivels, and fairleads electropolished for improved fatigue resistance and seawater corrosion protection in permanent mooring applications.
Subsea structural connectors, platform deck hardware, and splash zone fittings — electropolished for maximum resistance to the most corrosive zone in marine service.
Outboard and inboard engine components, drive shafts, and fuel system fittings electropolished for improved corrosion resistance and reliability in marine service environments.

Electropolishing is a precise and controllable process for eliminating defects from the surface of metal parts. But it’s not the only finishing process available to manufacturers; there are mechanical, chemical and plating processes that can remove defects and improve the…
Metal fabrication for parts used in the medical and electronics industries can involve dimensions as small as a grain of rice — or even a strand of hair. At that scale, surface defects may be invisible to the naked eye,…
While stainless steel is known for its corrosion resistance, it contains iron, which is susceptible to corrosion, especially if parts are frequently exposed to moisture or harsh environments. Contamination left behind by machining processes can also impede the corrosion resistance…
Electropolishing is a highly controlled electrochemical process that directly impacts surface integrity, corrosion resistance, cleanliness, and performance.
