Duplex Steel S31803 is an exceptional material known for its balanced composition of chromium, nickel, molybdenum, and nitrogen. This synergy grants it a unique two-phase microstructure, which delivers outstanding mechanical properties. It offers remarkable yield strength and excellent toughness, far surpassing common stainless steels. Its resistance to stress corrosion cracking is particularly notable, making it a robust choice for demanding environments where both strength and corrosion resistance are non-negotiable.
