Steve Flanges is a well-respected manufacturer and supplier located in Canberra, Australia, known for delivering top-notch Duplex Steel Seamless Tubing. This tubing is celebrated for its remarkable strength, resistance to corrosion, and long-lasting durability. Crafted using cutting-edge seamless extrusion techniques, these tubes boast smooth internal surfaces, precise dimensions, and outstanding performance even under high pressure and temperature. Steve Flanges offers Duplex Steel Seamless Tubing in a variety of grades, sizes, and wall thicknesses, all adhering to international standards. These tubes are perfect for demanding applications across industries like oil and gas, chemical processing, desalination, and power generation, where reliability and the ability to withstand harsh conditions are crucial.
The composition of Duplex Steel Seamless Tubing primarily includes iron, chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), and nitrogen. This unique dual-phase microstructure combines the strength of ferritic steel with the ductility of austenitic steel. The tubing exhibits high tensile strength ranging from 700–950 MPa and a yield strength of about 450–550 MPa. Its well-balanced chemistry ensures excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. The seamless manufacturing process not only enhances structural integrity but also guarantees consistent performance in challenging environments.
