We are supplier of Alloy 2205 Seamless Tube
Because Duplex Stainless Steel Tubes are very beneficial, they are very popular all over the world. Its chemical composition includes two different metal classes. At room temperature, they are essentially an iron, nickel, and chromium alloy with two phases ferritic and austenitic stainless steel microstructure. The Duplex 2205 Tube material is rich in chromium and molybdenum. However, they contain less nickel than austenitic stainless steel grades. The Duplex Tube is corrosion resistant due to its composition.
Duplex Steel Tubes are the most sought after in heavy industries such as nuclear, oil and gas, chemical processing, and so on because they have properties of both ferritic and austenitic microstructures. They are extremely strong, robust, and ductile.
The high thermal conductivity of DSS heat exchanger tube allows for efficient heat transfer
The Duplex Heat Exchanger Tube’s high chromium concentration causes the alloy to produce a protective coating on the tube’s surface. This improves the corrosion resistance of the tubes through oxidation. Furthermore, the yield strength of Duplex Seamless Tube is nearly twice that of normal austenitic stainless steel.
The Duplex Boiler Tube’s wall thickness and cross section can be reduced without impacting its mechanical qualities. They will continue to perform at the same level. This is why Indian Duplex Stainless Steel Tube manufacturers recommend utilising high-quality duplex tubes for heat exchangers.
The fractional 2205 tubing is utilised in commercial applications that demand high strength and corrosion resistance. The fractional 2205 Duplex Stainless Steel Tubing is typically stocked in annealed tempered state and is available in welded or seamless tubing solutions. The fractional 2205 Stainless Steel Tubing options come in a variety of commercial ratings as well as custom diameters.
