What is Super Duplex stainless steel? Super Duplex stainless steel like Duplex stainless steel, is a mixed microstructure of austenite and ferrite (50/50). It has improved strength over ferritic and austenitic steel grades. The main difference is that the Super duplex has a higher Molybdenum and Chromium content. They give the material greater corrosion resistance.
