Steve Flanges is a well-respected manufacturer and supplier located in Canberra, Australia, known for delivering top-notch Duplex Steel Seamless Pipes. These pipes are celebrated for their remarkable strength, resistance to corrosion, and long-lasting durability. Crafted using cutting-edge seamless forming techniques, they feature an outstanding surface finish, a consistent structure, and the ability to handle high pressure with ease. Steve Flanges offers these Duplex Steel Seamless Pipes in a variety of grades, sizes, and wall thicknesses, all adhering to international standards. Built to withstand harsh conditions, these pipes are perfect for industries like chemical processing, oil and gas, desalination, and power generation, where reliability and performance are absolutely essential.
The composition of Duplex Steel Seamless Pipes includes iron, chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), and nitrogen. This distinctive duplex microstructure merges the toughness and weldability of austenitic steel with the high strength and stress corrosion resistance of ferritic steel. These pipes boast a tensile strength ranging from 700–950 MPa and a yield strength of about 450–550 MPa. Their well-balanced composition offers excellent protection against pitting, crevice corrosion, and chloride stress corrosion cracking, ensuring they remain durable even in challenging environments.
