Super Duplex Steel Sheets, Plates & Flanges are manufactured from a high-alloy stainless steel containing significant amounts of chromium, nickel, molybdenum, and nitrogen, with controlled additions of iron, manganese, silicon, carbon, and other alloying elements. Its carefully balanced duplex microstructure, consisting of both austenitic and ferritic phases, provides an excellent combination of high mechanical strength, corrosion resistance, toughness, and resistance to localized forms of corrosion. The high chromium content contributes to strong resistance against general corrosion and oxidation, while molybdenum and nitrogen improve resistance to pitting, crevice corrosion, and chloride-induced attack, particularly in seawater and other aggressive environments. Nickel helps maintain the desired duplex structure and contributes to overall corrosion resistance and toughness. Super Duplex Steel Sheets, Plates & Flanges can be supplied in different thicknesses, widths, lengths, flange dimensions, pressure classes, face types, dimensional tolerances, heat-treatment conditions, and surface finishes according to specific engineering and fabrication requirements. With their combination of high tensile and yield strength, excellent chloride corrosion resistance, stress corrosion cracking resistance, toughness, durability, and reliable performance in demanding environments, Super Duplex Steel Sheets, Plates & Flanges are widely used in oil and gas, offshore and marine, chemical processing, petrochemical, seawater and desalination, power generation, pollution-control, pulp and paper, and other corrosion-intensive industrial applications.

In the annealed condition, Super Duplex Steel Sheets, Plates & Flanges provide an excellent balance of high mechanical strength, corrosion resistance, toughness, and resistance to localized corrosion, making them well suited for demanding industrial and engineering environments. They are particularly effective in applications exposed to seawater, chlorides, brine, acidic solutions, high-pressure fluids, and other aggressive operating conditions where dependable material performance is essential. The alloy’s high chromium content provides strong resistance to general corrosion, while molybdenum and nitrogen improve protection against pitting and crevice corrosion in chloride-rich environments. Its duplex austenitic-ferritic structure also provides good resistance to chloride stress corrosion cracking while offering higher strength than many conventional austenitic stainless steels. Super Duplex Steel Sheets, Plates & Flanges are widely used in offshore oil and gas systems, marine equipment, chemical processing plants, petrochemical facilities, desalination units, seawater handling systems, power generation, pulp and paper, pollution-control equipment, and other high-performance industrial applications. Depending on their dimensions and configuration, these products can be fabricated into pressure vessels, storage tanks, piping components, structural parts, flanges, covers, heat-exchanger components, pump and valve assemblies, and other critical equipment. With their combination of high strength, corrosion resistance, toughness, stress corrosion cracking resistance, durability, and excellent performance in chloride-containing environments, Super Duplex Steel Sheets, Plates & Flanges are a dependable choice for applications requiring long-term service reliability.

Composition of Super Duplex Steel Sheets & Plates
Super Duplex Steel Sheets, Plates & Flanges are produced from a high-alloy stainless steel chemistry containing significant levels of chromium, nickel, molybdenum, and nitrogen, together with controlled amounts of iron, manganese, silicon, carbon, and other alloying elements. The high chromium content provides strong resistance to general corrosion and oxidation, while molybdenum significantly improves resistance to pitting, crevice corrosion, and localized attack, especially in chloride-containing environments. Nitrogen strengthens the alloy and supports the formation and stability of its balanced austenitic-ferritic duplex microstructure, contributing to high mechanical strength and improved resistance to chloride-induced stress corrosion cracking. Nickel helps maintain the desired phase balance while also contributing to toughness and overall corrosion performance.
