Corrosion Proof 2205 Duplex Stainless Steel Bar - 3/4" Square, Saltwater Application
2205 duplex stainless steel bar (3/4" square) redefines durability in hyper-corrosive saltwater environments. Merging austenitic and ferritic microstructures, this dual-phase alloy delivers twice the yield strength of conventional 316 stainless steel while excelling in chloride-rich settings like offshore platforms, desalination plants, and subsea pipelines. Engineered to resist pitting, crevice corrosion, and stress corrosion cracking (SCC), it thrives in seawater temperatures up to 80°C. The square profile enhances load distribution and welding efficiency, making it ideal for modular marine infrastructure and next-gen blue energy systems.

① Dual-Phase Defense
Austenitic-ferritic microstructure blocks chloride ion penetration,
outperforming single-phase alloys in splash zones and tidal
environments.
② Biofouling Resistance
Optional graphene-infused coatings inhibit marine organism
adhesion, reducing maintenance for offshore wind turbine
foundations.
③ Zero SCC Risk
Nitrogen-enhanced matrix prevents stress corrosion cracking in
high-pressure, high-salinity subsea pipelines.
④ Green Credentials
Low-carbon production aligns with EU Taxonomy and offshore
decarbonization mandates.
⑤ Smart Integration
Embedded RFID tags (on request) enable real-time corrosion
monitoring via IoT-enabled asset management systems.
⑥ Modular Fabrication
Precision square bars simplify assembly in floating solar farms,
hydrogen electrolysis platforms, and wave energy converters.
Why This Product?
Beyond traditional marine engineering, the 2205 duplex bar bridges
material innovation and climate resilience. Its unmatched saltwater
durability, IoT-ready features, and eco-design make it pivotal for
sustainable ocean economies, where corrosion is not just a
challenge—it’s an existential threat.
