Duplex Steel is composed of both ferritic and austenitic structures, giving it enhanced strength and toughness compared to standard austenitic steels. This unique blend also provides excellent weldability, particularly in thicker sections. Duplex steel offers superior resistance to stress corrosion cracking, a significant advantage over typical austenitic steels.
