Duplex 2507 stainless steel, an advanced super duplex material, features a low carbon content (up to 0.03%), along with approximately 25% chromium, 7% nickel, and 4% molybdenum. Designed to meet the highest demands for strength and corrosion resistance, this alloy is ideal for applications in chemical process equipment, the petrochemical industry, and seawater systems. The high levels of chromium, molybdenum, and nitrogen provide stellar resistance against pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
Daxun Alloy possesses deep expertise in international specifications for super duplex seamless pipes, allowing us to deliver the perfect products to our clients. Our competitive pricing, superior quality, and prompt delivery have earned us a reputation as one of China's foremost super duplex pipe suppliers.
Super duplex seamless pipes are crucial in the oil and gas industry and indispensable for high-salinity horizontal wells or brine injection wells used for enhanced oil recovery. Renowned for their impressive strength and resistance to corrosion, fatigue, and erosion, ASTM A790 S32750 pipes can withstand uniform corrosion from organic acids like acetic and formic acids. These pipes also offer excellent thermal conductivity and energy absorption, ensuring high durability. With superior machinability and weldability, Werkstoff 1.4410 pipes experience minimal deformation when heated, ensuring reliable flanges and connections. Our 2507 Super Duplex Pipes are widely employed in chemical processing heat exchangers, offshore oil and gas processing, and petrochemical manufacturing, meeting international standards and serving industries worldwide.
