duplex rolled welded stainless steel square tube
Super Duplex has all the benefits of other duplex steels, specifically the strength benefits of their biphasic structural composition of equal parts austenitic and ferritic stainless steel. This microstructure makes all duplex steels around twice as strong as regular single structure ferritic or austenitic steels, but Super Duplex has a higher chromium and molybdenum content, giving it considerably increased resistance to corrosion than its counterparts.
As an alloy, the benefits of using Super Duplex 2507 are numerous. From corrosion resistance to strength, businesses around the world appreciate these properties of 2507 Super Duplex Seamless. 2507 Super Duplex is a super duplex stainless steel containing 25% chromium, 4% molybdenum and 7% nickel designed for demanding applications requiring exceptional strength and corrosion resistance such as chemical process, petrochemical and seawater equipment . The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and low coefficient of thermal expansion.
