S31803 Duplex Steel Flanges are a type of flange made from duplex stainless steel with the UNS designation of S31803. Duplex stainless steel is a type of steel that has a two-phase microstructure consisting of both austenitic and ferritic phases. S31803 is a common duplex stainless steel grade with good resistance to corrosion, high strength, and good weldability.S31803 Duplex Steel Flanges are used in a wide range of applications that require resistance to corrosion and high strength. They are commonly used in the oil and gas industry, chemical processing plants, and marine applications. These flanges are available in different sizes, pressure ratings, and types, including slip-on, weld neck, socket weld, blind, and threaded.
