Duplex Steel Forgings are produced from alloys with a balanced austenitic and ferritic microstructure. The composition typically includes chromium, nickel, molybdenum, and nitrogen, providing enhanced corrosion resistance and mechanical strength. High chromium and molybdenum content improve resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanically, duplex steel forgings offer high yield and tensile strength, excellent toughness, and good fatigue resistance. These properties ensure reliable performance under high pressure and moderate-to-high temperature conditions.

Duplex Steel Forgings are extensively used in industries requiring high strength and corrosion resistance. Common applications include oil and gas equipment, petrochemical plants, pressure vessels, heat exchangers, valves, flanges, and pump components. They are also used in marine engineering, offshore platforms, desalination plants, and chemical processing systems. Due to their excellent resistance to chlorides and aggressive environments, duplex steel forgings are ideal for critical load-bearing and high-pressure applications where durability and safety are paramount.
