UNS S31803 Slip on flange and Duplex 2205 flanges manufacturer in India
One of the most popular duplex stainless steel grades for moderately high temperatures is alloy 2205. What makes this alloy popular is its high mechanical strength along with good corrosion resistance properties. Duplex Steel Flanges manufacturer in India recommends using this alloy between a temperature of 572°F to -122°F.
The use of an alloy for a particular application will depend on its performance at certain temperatures. Beyond this temperature range, the material becomes brittle and loses both its ductility and toughness. To achieve maximum benefits from grade 2205 duplex ss flange is it necessary to follow temperature protocols to avoid application failure. Typically used across industrial sectors such as petrochemical, paper plants, chemical, oil, and gas, this alloy derives its strength from its dual microstructure and good mechanical properties. Erosion corrosion, which affects most steel alloys does not occur in the Duplex 2205 flanges. This component has toughness and corrosion resistance that make it durable. While this alloy contains nickel, which stabilizes austenite, there is a higher content of chromium, which imparts the duplex blind flange with ferritic properties. So, while this alloy inherits good ductility and good resistance to corrosion, it also inherits the vulnerability of SCC in the presence of chlorine ions. Unlike austenitic stainless steel grades, ferritic ones are highly resistant to the effects of chlorine induced. Grade 2205, contains both austenite and ferrite in an equivalent proportion, which makes the UNS S31803 Slip on flange resilient to chlorine Sytress related corrosion cracking. Aside from being resistant to chlorine ions, what makes this alloy useful is its resistance to sulfides. Sulfides or hydrogen that get deposited in the walls of flanges causes load on them, causing them to crack. Because of its resistance to Sulfides, most duplex flanges suppliers recommend using them in environments that use Hydrogen sulfide.
