Duplex 2507 stainless steel, renowned for its super duplex properties, features a meticulously balanced composition of low carbon (up to 0.03%), chromium (~25%), nickel (~7%), and molybdenum (~4%). This alloy is meticulously engineered to meet the rigorous demands of high-strength, corrosion-resistant applications, making it ideal for chemical process equipment, the petrochemical industry, and seawater systems. Its exceptional resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking is attributed to its high chromium, molybdenum, and nitrogen content.
Daxun Alloy possesses unparalleled expertise in international specifications for super duplex seamless pipes, enabling us to supply the perfect products to our discerning clients. We have cemented our reputation as one of China's top super duplex pipe suppliers through our competitive pricing, superior quality, and prompt delivery.
Super duplex seamless pipes play crucial roles in the oil and gas industry and are indispensable in high-salinity horizontal wells or brine injection wells for enhanced oil recovery. Renowned for their impressive strength and resistance to corrosion, fatigue, and erosion, ASTM A790 S32750 pipes also exhibit excellent resistance to uniform corrosion from organic acids like acetic and formic acids. These pipes are celebrated for their exceptional thermal conductivity and energy absorption, making them highly durable. With superior machinability and weldability, Werkstoff 1.4410 pipes experience minimal deformation under heating, ensuring reliable flanges and connections. Our 2507 Super Duplex Pipes are widely utilized in heat exchangers for chemical processing, offshore oil and gas processing, and petrochemical manufacturing, meeting the highest international standards and serving industries across the globe.
