Sadiki Metals, located in Kinshasa, Congo, has earned a solid reputation as a reliable manufacturer and supplier of Super Duplex Steel Square Bars. They pride themselves on delivering top-notch products that are built for strength, performance, and resistance to corrosion. Thanks to their cutting-edge manufacturing technology and rigorous quality control processes, Sadiki Metals guarantees that every square bar adheres to international standards for precision and durability. These Super Duplex Steel Square Bars strike an ideal balance between high mechanical strength and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. As a result, they find extensive use in various industries, including oil and gas, chemical processing, marine engineering, and construction, providing dependable performance even in the harshest conditions.
Super Duplex Steel Square Bars are primarily made up of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, which together offer outstanding corrosion resistance and strength. Their unique microstructure features both austenitic and ferritic phases, giving them impressive toughness and excellent resistance to chloride stress corrosion cracking. With tensile strength reaching up to 800–1000 MPa and yield strength around 550 MPa, they also boast remarkable hardness and ductility. These characteristics make Super Duplex Steel perfect for high-pressure and high-temperature applications, ensuring stability, durability, and resistance to mechanical wear and fatigue.
