Super Duplex Steel Flanges

Super Duplex is also w dual structure alloy made using austenitic and ferritic steel grades. Super Duplex steel flanges are developed specifically to work in the Oil & Gas Industries. The corrosion resistance in these flanges is superior.

 

The chromium and molybdenum in super duplex in more in comparison to that of duplex steels. The high strength and corrosion resistance is prominent in SD Steels, owing to the dual-phased structure. Chloride environments do not cause much damage to the internal structure of Super Duplex Steel Flanges. These properties makes super duplex steels usable in many applications. Nickel and molybdenum is added in lesser quantities in SD. The lesser alloy amounts makes Super Duplex steels highly cost effective. When compared to single structures of only austenitic and ferritic steels, the tensile strength and yield strength is high. Flanges made from Super Duplex steels are usable in marine applications, without taking much surface damage. Applications offshores coastline, fire fighting systems, subsea coastlines and injector and ballast systems make use SD Flanges. Oils and Gas plants make extensive use of Super Duplex Steel Flanges.
