Duplex 2507 stainless steel is a superior duplex material characterized by low carbon content (up to 0.03%), with approximately 25% chromium, 7% nickel, and 4% molybdenum. This high-performance steel is designed to fulfill the demanding requirements of applications requiring exceptional strength and corrosion resistance. Ideal for chemical processing equipment, the petrochemical industry, and seawater applications, it exhibits outstanding resistance to chloride-induced stress corrosion cracking. Its high chromium, molybdenum, and nitrogen content confer excellent resistance to pitting, crevice corrosion, and beyond.
Daxun Alloy excels in understanding international specifications for super duplex seamless pipes, providing our customers with superior products. Renowned as one of China's leading super duplex pipe suppliers, we are committed to offering competitive pricing, exceptional quality, and timely delivery.
Super duplex seamless pipes are indispensable in the oil and gas sector, especially in high-salinity horizontal wells or brine injection wells, significantly enhancing oil recovery. These pipes are renowned for their incredible strength and resistance to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes withstand uniform corrosion from organic acids like acetic and formic acids. Our Super Duplex Stainless Steel Seamless Pipes exhibit impressive thermal conductivity and energy absorption. Moreover, Super Duplex Hollow Pipes are easily machinable and weldable. With Werkstoff 1.4410, deformation is minimal when heated, ensuring robust flanges and connections. 2507 Super Duplex Pipes are essential in heat exchangers used in chemical processing, offshore oil and gas, and petrochemical manufacturing. Our 2507 Super Duplex Stainless Steel Pipes adhere to global standards, serving numerous international industries.
