Super Duplex 2507 Stainless Steel Sheet & Plate (UNS S32750)
PREN ≥ 40 | Extraordinary Corrosion Resistance | High-Strength Solutions for Extreme Environments
Exceptional PREN Value: With a Pitting Resistance Equivalent Number (PREN) above 40, it outperforms almost all 300-series and standard duplex steels in chloride environments.
Superior Mechanical Strength: Offers significantly higher yield strength than 2205, allowing for extreme weight reduction in structural designs without compromising safety.
Erosion & Cavitation Resistance: Highly resistant to erosion-corrosion and fatigue, making it the top choice for high-speed moving parts in seawater.
Corrosive Media Stability: Outstanding resistance to organic acids, inorganic acids, and high-concentration chloride solutions.
Offshore Oil & Gas: Subsea manifolds, risers, and hydraulic control lines in deep-sea environments.
Desalination Plants: High-pressure RO (Reverse Osmosis) systems and seawater handling equipment.
Chemical Processing: Production of nitric acid, organic acids, and fertilizer where chloride contamination exists.
Marine Hardware: High-load structural components for specialized naval vessels and chemical tankers.
Certified Quality: Direct supply from Tisco / Baosteel; every plate is delivered with an authentic 3.1 Mill Test Certificate.
Customized Fabrication: Precision water-jet or laser cutting to prevent heat-affected zone (HAZ) issues in super duplex alloys.
Secure Logistics: Heavy-duty, sea-worthy packaging designed for international long-haul transit to ensure flat and scratch-free delivery.
Technical Support: Our engineers provide consultation on welding and forming 2507 for your specific project needs.
