Duplex and Super Duplex steels are austenitic-ferritic whose main characteristic is the resistance to intergranular corrosion and pitting.
Their mechanical properties are generally superior to those of conventional stainless steels.
Temperature is a limiting factor in their use (300°C). The Austenitic-ferritic nature requires special attention for welded construction.
