ASTM A789 Duplex Seamless Stainless Steel Pipe With Cold Rolled
Duplex Stainless Steel Tube Description
Duplex stainless steel tubes are a type of stainless steel tubing that contain a two-phase microstructure consisting of both austenitic and ferritic stainless steel. This combination provides a higher strength and better corrosion resistance compared to conventional austenitic stainless steels.
Duplex stainless steel tubes typically contain a roughly equal mixture of austenitic and ferritic phases, with chromium, nickel, molybdenum, and sometimes nitrogen for enhanced properties.
Duplex stainless steel tubes are a valuable material choice for applications requiring a balance of high strength and corrosion resistance in challenging environments.
Duplex Stainless Steel Tube Application
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.
