Duplex 2507 stainless steel, renowned as a super duplex material, showcases a low carbon composition (up to 0.03%) along with approximately 25% chromium, 7% nickel, and 4% molybdenum. This alloy is meticulously engineered to cater to high-strength, corrosion-resistant applications, making it ideal for chemical process equipment, the petrochemical sector, and seawater systems. The high chromium, molybdenum, and nitrogen content ensures exceptional resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
At Jiangsu Daxun Alloy, our extensive expertise in international specifications for super duplex seamless pipes empowers us to deliver precisely the products our clients need. We have cemented our position as one of China's premier super duplex pipe suppliers through our competitive pricing, unmatched quality, and timely delivery.
Our super duplex seamless pipes play pivotal roles in the oil and gas industry, especially in high-salinity horizontal wells or brine injection wells for enhanced oil recovery. Known for their exceptional strength and corrosion resistance, ASTM A790 S32750 pipes also excel in withstanding uniform corrosion from organic acids such as acetic and formic acids. These pipes offer superior thermal conductivity and energy absorption, ensuring high durability. With easy machinability and weldability, Werkstoff 1.4410 pipes exhibit minimal deformation under heating, ensuring reliable flanges and connections. Our 2507 Super Duplex Pipes are extensively used in heat exchangers for chemical processing, offshore oil and gas processing, and petrochemical manufacturing, consistently meeting international standards and fulfilling global industry demands.
