Duplex Steel 2205 earns its strength from a balanced composition of chromium, nickel, molybdenum, and nitrogen. This unique formula gives it an excellent mix of properties, offering the toughness of austenitic steels and the strength of ferritic grades. The result is a coil material with impressive yield strength and strong resistance to stress corrosion cracking. It also stands up well against pitting and crevice corrosion, making it a robust choice for challenging conditions.
