Duplex Steel

Duplex steels are called so for their two structural phases i.e. austenitic and ferritic. Duplex steel are known for their good mechanical properties. These steels also have excellent corrosion resistant properties.

Duplex Steel is stronger than regular austenitic or ferritic steel types. Better toughness and ductility are traits executed better in duplex steels, when compared to ferritic steels. The nitrogen, chromium, molybdenum and nitrogen content make it immune from chloride pitting and crevice corrosion resistance. Stress-corrosion cracking resistance in excellent in duplex steels. Duplex steel have lower nickel and molybdenum content when compared to other austenitic steels. The lower alloying content of elements make these steel types much cost effective. The sectional thickness of duplex steels can be altered, due to the increased yield strength when compared to normal austenitic steels.  Duplex steels are used in brewing tanks, process plants, hot water tanks, and more, owing to their stress corrosion cracking resistance. Overall, higher strength, greater resistance to corrosion, and lower pricing makes duplex steels more popular.
