Duplex steel welded tubing is produced by merging austenitic and ferritic stainless steels, which are usually composed of 22% chromium, 5% nickel, molybdenum, and trace nitrogen. The balanced composition provides enhanced corrosion resistance, especially in chloride-rich settings. The tubing is offered high tensile strength (upto 620 MPa), a yield strength of approximately 450 MPa, and satisfactory ductility. Most notable among the advantages are excellent pitting and crevice corrosion resistance, improved weldability, resistance to stress corrosion cracking, and cost-effectiveness—evidently making it a material of choice for industries functioning under aggressive environments.

Welded duplex steel tubing finds widespread use in sectors that demand both strength as well as corrosion resistance. It is used in the oil and gas industry for pipelines, heat exchangers, and offshore platforms. In chemical processing, it effectively deals with high-pressure corrosive fluids. Its high resistance to saltwater-induced corrosion makes it suitable for use in the marine industry, including desalination plants and shipbuilding. It is also applied in power plants, pulp and paper processing, and water treatment plants where exposure to abrasive media and high mechanical stress requires a cost-effective and robust tubing solution.
