Duplex Steel 2205 Sheet & Plate Features

• » High Mechanical Strength: Offers roughly double the yield strength of austenitic stainless steels, allowing for significant weight reduction and cost savings in structural designs.
• » Superior SCC Resistance: The ferritic-austenitic structure provides excellent resistance to chloride-induced stress corrosion cracking (SCC), a common vulnerability in 300-series alloys.
• » Enhanced Pitting and Crevice Resistance: With a PREn value of 34 or higher, it outperforms Grade 316 in resisting localized corrosion in aggressive chloride environments.
• » Excellent Fatigue Strength: Exhibits high fatigue strength and resistance to erosion-corrosion, making it ideal for rotating parts and high-velocity fluid systems.
• » Good Weldability: Can be welded using most standard fusion techniques; the balanced microstructure ensures the heat-affected zone (HAZ) retains its mechanical and corrosion properties.
• » Low Thermal Expansion: Features a coefficient of thermal expansion closer to carbon steel than austenitic stainless steel, reducing thermal stresses in heat-exchange equipment.
• » Cost Efficiency: Provides a more stable pricing structure due to lower nickel content compared to high-alloy austenitic grades, while delivering superior performance.
• » Wide Temperature Range: Effectively maintains its properties in service temperatures ranging from -50°C up to 300°C, suitable for diverse industrial climates.
