Duplex Steel Round Bar are in big demand today and the reason for this is that the characteristics of Duplex 2205 are many and these include having a general corrosion resistance that is good, good workability and weldability, sulfide stress corrosion resistance that is good, offers high resistance to chloride stress corrosion cracking, has a high strength and offers good resistance to crevice corrosion and chloride pitting. Duplex Steel F60 UNS S32205 Round Bars has Nickel content between 1.5% - 8% (moderate amounts) and it has between 18% - 28% chromium (high level).
Another reason why Duplex Steel bar is widely used today is because UNS S32205 F60 Round Bars not only has excellent mechanical properties, it is extremely corrosion resistant. Due to the balanced microstructure (nearly equal volume percentages of both austenite and ferrite) of Duplex 2205, as well as its chemical composition, it has a very high capacity to resist corrosion. Because of this very duplex nature, 2205 Duplex Round Bar exhibits properties that are characterized by both ferritic stainless steels, as well as by austenitic stainless steels. In the case of austenitic stainless steels, Duplex 2205 rod has double the strength as compared to them, in certain cases. Most of the time, as far as ferritic stainless steels go, Duplex 2205 is tougher than these. Today, ASTM A276, A479 UNS S32205 F60 Round Bars is used in a wide number of applications such as piping and heat exchangers, flue gas desulfurization equipment, chip pre-steaming vessels, bleach washers, oil field piping and heat exchangers, pulp mill digesters, chemical process vessels, food processing equipment, to name a few.
