Super Duplex Steel DIN 1.4410 Flanges

Super duplex steel DIN 1.4410 flanges are austenitic-ferritic stainless steel designed for extreme environmental and pressure applications. Its chemical composition dictates its superior performance: a chromium content of 23-28%, a high molybdenum of 4–6%, an even higher nickel content of 6–8%, and some trace elements such as nitrogen, silicon, phosphorus and manganese. This combination ensures not only durability but exceptional corrosion resistance and thermal stability.

DIN 1.4410 Super Duplex are super chromium-nickel-molybdenum-n proprietary alloy flanges used in industrial piping due to their superior mechanical and corrosion-resistant properties. They are excellent for wet sour gas and corrosive environments, making them ideal for outdoor systems, especially those exposed to coastal regions. Furthermore, these flanges perform well against sea water, acids, chlorides and heat exchangers, thus making them the go-to fittings for any process industry like wastewater treatment plants, desalination equipment and oil production platforms. Other properties of the Super Duplex steel DIN1.4410 include higher temperature strength than austenitic stainless steel alloys. Additionally, they also have good weldability while providing excellent impact resistance. Also, do explore our din 1.4410 plates.
