Duplex 2507 stainless steel is a high-performance super duplex material featuring low carbon content (up to 0.03%), and substantial amounts of chromium (~25%), nickel (~7%), and molybdenum (~4%). Engineered to fulfill the exacting demands of applications requiring superior strength and corrosion resistance, this steel is ideal for chemical process equipment, the petrochemical sector, and marine environments. Duplex 2507 stainless steel stands out for its impressive resistance to chloride-induced stress corrosion cracking. Its high chromium, molybdenum, and nitrogen content confer exceptional resistance to pitting, crevice, and other forms of corrosion.
Daxun Alloy is adept at navigating international specifications for super duplex seamless pipes, armed with a deep product knowledge to meet our customer's needs expertly. Our competitive pricing, unparalleled quality, and punctual delivery make us one of China's top-tier super duplex pipe suppliers.
Super duplex seamless pipes are essential in the oil and gas industry and are often used in high-salinity horizontal wells or brine injection wells to enhance oil recovery. Renowned for their exceptional strength and corrosion resistance, these pipes also withstand fatigue and erosion. ASTM A790 S32750 pipes specifically combat uniform corrosion from organic acids such as acetic and formic acids. These pipes boast excellent thermal conductivity and energy absorption properties. Additionally, Super Duplex Hollow Pipes are highly machinable and weldable. Pipes marked with Werkstoff number 1.4410 exhibit minimal deformation upon heating, preventing defective flanges or connections. 2507 Super Duplex Pipes find application in heat exchangers within chemical processing, offshore oil and gas processing, and petrochemical manufacturing. Our 2507 Super Duplex Stainless Steel Pipes adhere to international standards and are trusted by various global industries.
