Discover the unparalleled properties of Duplex 2507 stainless steel, a super duplex material engineered to perfection. With a low carbon content (up to 0.03%) and enriched with chromium (~25%), nickel (~7%), and molybdenum (~4%), this alloy is designed to meet the rigorous demands of high-strength, corrosion-resistant applications. Its exceptional composition makes it ideal for chemical process equipment, the petrochemical industry, and seawater systems. Thanks to its high chromium, molybdenum, and nitrogen content, Duplex 2507 offers remarkable resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, setting a new standard in material performance.
With unrivaled expertise in international specifications, Daxun Alloy supplies the perfect super duplex seamless pipes tailored to our clients' needs. Our reputation as one of China's top super duplex pipe suppliers is built on competitive pricing, superior quality, and prompt delivery, making us a trusted partner in the industry.
Super duplex seamless pipes from Daxun Alloy play a critical role in the oil and gas industry, proving indispensable in high-salinity horizontal wells or brine injection wells for enhanced oil recovery. Renowned for their impressive strength, resistance to corrosion, fatigue, and erosion, ASTM A790 S32750 pipes also exhibit uniform resistance to organic acids like acetic and formic acids. These pipes offer excellent thermal conductivity and energy absorption, ensuring durability and reliability. With easy machinability and weldability, Werkstoff 1.4410 pipes maintain minimal deformation under heating, guaranteeing secure 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, complying with international standards and serving industries globally.
