Duplex stainless steel pipes, plates, fittings, and forgings exhibit a microstructure comprising approximately equal parts of austenite and a ferrite matrix. This composition, in tandem with a general alloying level, imparts notable characteristics. These alloys exhibit high strength compared to standard austenitic steels like type 316L, ensuring robustness in various applications. Their corrosion resistance extends across diverse environments, making them well-suited for challenging conditions. Notably, they demonstrate elevated resistance to chloride-induced stress corrosion cracking (CSCC) and pitting attacks in chloride-rich environments, such as seawater. In the offshore oil/gas, chemical, and petrochemical process industries, these alloys find expanding applications, encompassing pipework systems, flowlines, risers, manifolds, and more. Additionally, the filler metal derived from these alloys is utilized for welding stainless structures requiring exceptionally high strength.
