Duplex Steel S31803 is renowned for its balanced composition, primarily a blend of chromium, nickel, molybdenum, and nitrogen. This unique mix gives the tubing an excellent combination of high strength and exceptional resistance to corrosion, including stress corrosion cracking. It effectively bridges the gap between standard austenitic and ferritic steels, offering roughly double the yield strength of conventional stainless grades, making it both tough and durable for challenging environments.
