Duplex 2507 stainless steel is an advanced super duplex material with a low carbon content (up to 0.03%) and high levels of chromium (~25%), nickel (~7%), and molybdenum (~4%). Designed to meet the stringent demands of high-strength and corrosion-resistant applications, this steel excels in chemical process equipment, the petrochemical industry, and seawater equipment. Its high resistance to chloride-induced stress corrosion cracking, along with exceptional resistance to pitting, crevice corrosion, and other forms of corrosion, makes it ideal for harsh environments.
At Daxun Alloy, we have an in-depth understanding of international specifications for super duplex seamless pipes. This knowledge, coupled with our commitment to competitive pricing, excellent quality, and timely delivery, makes us one of China's premier super duplex pipe suppliers.
Super duplex seamless pipes are essential in the oil and gas industry, particularly in high-salinity horizontal wells and brine injection wells aimed at enhancing oil recovery. These pipes are notably strong, resistant to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes resist uniform corrosion from organic acids like acetic and formic acids. With excellent thermal conductivity and energy absorption properties, they are also easily machinable and weldable. Werkstoff 1.4410 pipes exhibit minimal deformation when heated, preventing faulty flanges or connections. Consequently, 2507 Super Duplex Pipes are extensively used in heat exchangers for chemical processing, offshore oil and gas processing, and petrochemical manufacturing. Our 2507 Super Duplex Stainless Steel Pipes adhere to international standards and serve various industries worldwide.
