The Duplex steel tube is a Fe-Ni-Cr-based alloy that has a two-phase ferritic-austenitic stainless-steel microstructure. The advantage of combining ferritic and austenitic grades in these tubes is that the resultant metal has a metallurgical structure that exhibits two phases & thus benefits from the properties of both microstructures. Some steel tubes also contain the alloy elements such as Mo, Cu, Nb, Ti, and N which enables superior metallurgical and mechanical properties.
Duplex Stainless steel products are characterized by high chromium content of around 19–28% and molybdenum content of up to 5% and lower nickel contents than austenitic stainless steel. Some of the widely recommended duplex stainless steel tubes are the 2205 seamless pipe containing 22% Chromium and 5% Nickel contents. These tubes have key features such as high strength, Rockwell hardness, ductility, extraordinary mechanical and physical properties, and superb structural stability.
Grade
Some of the crucial applications of duplex tubes are gas nuclear and chemical processing, nuclear power plant, production of seawater, heat exchangers, chemical containers of high temperature in chloride environments, and desalination plants.
These types of tubes have amazing immunity against chloride pitting, stress cracking, crevice, and other general corrosions. Prism TuboTech Pvt. Ltd. offers the finest Commercial quality SS duplex tubes and other products for various business purposes in the entire industry along with exceptional key features and speed delivery service to our consumers.
