    2205 Duplex Stainless Steel Bar Corrosion Proof 3/4" Square Customized

    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.


    2. Technical Specifications

    ParameterDetails
    Material2205 Duplex Stainless Steel (UNS S32205/S31803)
    Element CompositionCr: 22–23%, Ni: 4.5–6.5%, Mo: 3–3.5%, N: 0.14–0.2%, Mn: ≤2%, Fe: Balance
    StandardASTM A276, EN 10088-1, NORSOK MDS D45

    Mechanical PropertiesTensile Strength: ≥795 MPa, Yield Strength: ≥550 MPa, Hardness: ≤310 HV
    Corrosion ResistancePREN ≥34, ISO 15156-3 (NACE MR0175) compliant for sour service
    CertificationsDNV-GL, ABS, ISO 20904 (sustainable sourcing)
    Eco-Innovation30% Recycled Content, Low-Carbon Production (≤1.8t CO₂/ton)

    3. Competitive Advantages

    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.


    4. Next-Gen Saltwater Applications

    • Blue Hydrogen Hubs: Structural frames for seawater electrolyzers and hydrogen storage units in coastal zones.
    • Deep-Sea Mining ROVs: Pressure-resistant bars for robotic arms and sensor mounts in brine pools.
    • Floating Desalination Barges: Pump shafts and brine concentrator components for mobile water treatment.
    • Arctic Offshore Drilling: Cryogenic-tolerant fasteners and pipeline supports resistant to ice abrasion.
    • Bio-Glass Reefs: Marine restoration structures with anti-corrosion bars to anchor artificial coral ecosystems.
    • Tidal Turbine Arrays: Rotor shafts and mooring systems enduring 24/7 seawater immersion and microbe attacks.
    • Zero-Discharge Aquaculture: Cage frames and feed systems for offshore fish farms with circular water flows.

    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.
