Super Duplex 2207 Sheet & Plate Features

• » Extreme Corrosion Resistance: With a PREn value exceeding 40, these plates provide maximum protection against pitting and crevice corrosion in seawater and high-chloride environments.
• » Exceptional Mechanical Strength: Offers significantly higher yield and tensile strength than both 300-series and standard Duplex 2205, allowing for substantial weight-saving designs.
• » Immunity to Stress Corrosion Cracking (SCC): The 25% chromium and balanced dual-phase structure provide near-immunity to chloride-induced SCC in temperatures up to 300°C.
• » High Thermal Conductivity: Features superior heat transfer capabilities compared to austenitic grades, reducing energy consumption in heat exchangers and boilers.
• » Superior Erosion and Fatigue Resistance: The high hardness and mechanical integrity make it ideal for parts subjected to high-velocity fluids and cyclic loading.
• » Low Thermal Expansion: Its coefficient of thermal expansion is similar to that of carbon steel, minimizing thermal stresses and distortions in welded assemblies.
• » Versatile Fabrication: Despite its high strength, the material exhibits good weldability and formability when using appropriate filler metals and controlled heat inputs.
• » Cost-Effective Longevity: While the initial cost is higher than standard grades, the extended service life and reduced maintenance in aggressive media provide a lower total life-cycle cost.
