ASTM A182 Duplex Steel F51, also known as UNS S31803 or URANUS 45N, is a highly corrosion-resistant and durable material widely used in various industries. These bars are a type of Duplex stainless steel, which exhibits a unique combination of properties due to its dual-phase microstructure consisting of both austenite and ferrite. This makes it superior to standard duplex steels, offering enhanced strength and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
