Super Duplex Steel 2507 Bars and Rods are made up mainly of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, which together create a well-balanced austenitic-ferritic microstructure. This unique blend gives it outstanding resistance to corrosion caused by chlorides, as well as pitting and stress corrosion cracking. The material boasts impressive mechanical strength, with a tensile strength ranging from about 800 to 1000 MPa and a yield strength of roughly 550 MPa. It also retains high hardness and toughness, even in freezing temperatures. Thanks to its exceptional weldability, fatigue resistance, and stability under high pressure, Super Duplex 2507 is perfect for tough industrial and structural applications.
