Duplex and super duplex stainless steels

These are biphasic stainless steels with a mixed crystalline grain structure of austenite and ferrite. They have good mechanical strength and good corrosion resistance, excellent ductility, and weldability.

Super duplexes are high performance duplex steels and combine the best characteristics of austenitic and ferritic steels. They bring their use to the highest level, even in the most critical conditions.

In Nicro they are used for the construction of naval components and for the smoke outlet pipes upstream of the scrubber.
