Duplex Steel Sheets & Plates are manufactured from a balanced austenitic-ferritic stainless steel composition containing chromium, nickel, molybdenum, nitrogen, and controlled amounts of carbon, manganese, silicon, and other alloying elements. This dual-phase structure provides an effective combination of high mechanical strength, corrosion resistance, toughness, and reliable performance in demanding service environments. The chromium content provides strong resistance to general corrosion and oxidation, while molybdenum and nitrogen improve resistance to pitting, crevice corrosion, and localized attack, particularly in chloride-containing environments. Nickel helps maintain the desired austenitic phase and contributes to the material’s toughness and corrosion performance, while the ferritic phase provides enhanced strength and resistance to stress-corrosion cracking. Duplex Steel Sheets & Plates can be supplied in different thicknesses, widths, lengths, cut-to-size dimensions, tolerances, heat-treatment conditions, and surface finishes according to specific fabrication and engineering requirements. With their combination of high tensile strength, excellent corrosion resistance, resistance to pitting and stress-corrosion cracking, toughness, weldability, and durability, Duplex Steel Sheets & Plates are widely used in oil and gas, chemical processing, petrochemical, offshore and marine, desalination, power generation, water treatment, pulp and paper, fertilizer, and other demanding industrial applications.

In the annealed condition, Duplex Steel Sheets & Plates provide an excellent combination of high mechanical strength, corrosion resistance, toughness, and resistance to localized corrosion, making them suitable for demanding industrial and engineering applications. They are particularly effective in environments involving chlorides, seawater, brackish water, chemical solutions, elevated temperatures, and other aggressive service conditions where long-term material reliability is important. The balanced chromium, molybdenum, nickel, and nitrogen content provides strong resistance to general corrosion, while the duplex austenitic-ferritic structure improves resistance to pitting, crevice corrosion, and stress-corrosion cracking. The annealed condition also provides a suitable balance of strength and ductility, supporting forming, fabrication, welding, and further processing according to application requirements. Duplex Steel Sheets & Plates are commonly used in oil and gas facilities, chemical processing plants, petrochemical equipment, offshore and marine systems, desalination plants, power generation, water treatment, pulp and paper equipment, fertilizer plants, and other demanding industrial applications. Depending on their thickness and dimensions, they can be fabricated into pressure vessels, storage tanks, process equipment, heat-exchanger components, piping sections, structural panels, liners, ducts, and other corrosion-resistant assemblies. With their combination of high strength, toughness, corrosion resistance, resistance to pitting and stress-corrosion cracking, weldability, and durability, Duplex Steel Sheets & Plates provide a dependable material solution for equipment operating in severe and corrosive environments.

Composition of Duplex Steel Sheets & Plates

Duplex Steel Sheets & Plates are produced from a carefully balanced austenitic-ferritic stainless steel composition containing chromium, nickel, molybdenum, nitrogen, and controlled levels of carbon, manganese, silicon, and other alloying elements. This dual-phase metallurgical structure gives duplex steel a strong combination of mechanical strength, corrosion resistance, toughness, and reliable performance in severe service environments. Chromium provides the primary resistance to general corrosion and oxidation, while molybdenum and nitrogen work together to improve resistance to pitting, crevice corrosion, and localized attack, especially in chloride-containing and marine environments. Nickel supports the formation of the austenitic phase and contributes to toughness and corrosion resistance, while the ferritic phase provides higher strength and improved resistance to stress-corrosion cracking. This balanced chemistry allows Duplex Steel Sheets & Plates to maintain their mechanical integrity under demanding pressure, temperature, and corrosive conditions. With their combination of high tensile and yield strength, excellent corrosion resistance, resistance to pitting and stress-corrosion cracking, toughness, weldability, and long-term durability, Duplex Steel Sheets & Plates are widely used in oil and gas, chemical processing, petrochemical, offshore and marine, desalination, power generation
