Aspirinox Alloys Inc. is one of the most trusted names when it comes to the production, sale, distribution and export of quality grade Duplex Steel 2205 Tubes. Provided to suit customer need and budget, our Duplex UNS S31803 Tubes is reputable for durability, resistance to corrosion, dimensional precision and smooth finish.


Our Duplex 2205 Seamless Tubing is available in a variety of shapes including round, hexagonal, rectangular, and hollow. We also offer different sizes, grades, and thicknesses. Duplex S31803 Seamless Tubes are characterized by good workability and weldability. In fact, Duplex 2205 Tubes, as the name suggests, incorporate a duplex structure, thus blending good qualities of an austenitic alloy (corrosion-resistance and hassle-free fabrication) and that of a ferritic alloy (considerable strength and resistance to stress corrosion cracking).


Our Duplex 2205 Cold Drawn Seamless Tubes have better mechanical properties and dimensional tolerance than corresponding seamless tubes that are hot finished. The Duplex UNS S31803 Electropolished Tubes are homogenous all through the material. We being leading Duplex 2205 Welded Tubes Suppliers, these tubes find application in such varied industries as chemical plants, industrial machinery, power, cement, and oil refinery.
