Super Duplex Steel

Super-Duplex steel are also a mixture of austenitic and ferritic steels. Super-duplex steels are developed for specific usage in oil & Gas industries.  Super Duplex steels also find applications in chemical industries. Superior corrosion resistance is a property of super-duplex steels.

The main difference between super-duplex and duplex steels is the higher molybdenum and chromium content in super-duplex steels. The dual phase structure is extremely balanced, which gives it a combination of high strength and corrosion resistance. The nickel and molybdenum is alloyed in lower amounts, making the steel more cost effective. It also has chloride resistance in chloride containing environments. The tensile and yield strength of super-duplex steels is also more, when compared to other austenitic and ferritic steel grades. Thickness of duplex and super-duplex steels can be altered, as per requirements without compromising on quality and durability. Super-duplex steel is applicable in many industries such as offshore coastlines, subsea control lines. Fire-fighting systems, heat exchangers, injection and ballast water systems, chemical processing and oil 7 gas.
