Ang Super Duplex adunay tanan nga mga benepisyo sa uban pang mga suplay sa duplex, partikular ang kusog nga mga benepisyo sa ilang Biphasic Struction of Parets Austlessic. This microstructure makes all duplex steels around twice as strong as regular single structure ferritic or austenitic steels, but Super Duplex has a higher chromium and molybdenum content, giving it considerably increased resistance to corrosion than its counterparts.
