The strength of Duplex Steel comes from its unique composition, a balanced blend of chromium, nickel, molybdenum, and nitrogen. This synergy gives the material impressive mechanical properties, including very high tensile strength and excellent resistance to stress corrosion cracking. It essentially offers the best of both worlds, combining the toughness of austenitic steels with the strength of ferritic grades, making it a remarkably resilient choice for challenging environments.
