Super Duplex stainless is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades. The main difference is that Super Duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance than standard duplex grades.
The balanced duel phase microstructure combines high strength with cost effective corrosion resistance particularly in high chloride environments. Super Duplex has the same benefits as its counterpart – it has lower alloying costs when compared with similar ferritic and austenitic grades with equipment corrosion resistance in chloride containing environments due to the material’s increased tensile and yield strength. In many cases this gives the purchaser the welcomed option of purchasing smaller thicknesses without the need to compromise on quality and performance.
NS S32750, F55, 1.4501 Duplex has enhanced pitting and crevice corrosion resistance compared with the ordinary austenitic or duplex types
This is due to the further additions of chromium, molybdenum, and nitrogen to these grades
UNS S32760, F55, 1.4501 combines high strength and good ductility with outstanding corrosion resistance. With UNS S32750, F55, 1.4501 having these attribute it is used in a wide range of marine, oil and gas environments
UNS S32750, F55, 1.4501 is the most common super duplex grade.
