  • Duplex Stainless Steel Benefits and Use | Special Piping ...

    Duplex stainless steel is a very useful metal that is used the world over. It gets its name from the fact that it consists of two different grades of metal. Essentially, Duplex is a Fe-Ni-Cr alloy that has a two-phase ferritic-austenitic stainless-steel microstructure when it is at room temperature.
