The Duplex Steel 2205 Flanges are high strength flanges that are used in extensively corrosive environments. They offer high corrosion resistance, much higher than general SS 316 flanges. These flanges are immune to chloride stress corrosion cracking and inter-granular pitting. The Duplex Steel 2205 Flanges also offer high oxidation resistance. The oxidation resistance of the flanges is barred by the embrittlement caused above 300°C. They are suitable for applications in temperatures below 300°C. These Flanges also offer great ductility with high toughness. Because of their hardness, these flanges are difficult for machining. Machining of these flanges can be enhanced by various processes.
The Duplex Steel 2205 Flanges are very popular because of their low cost and maintenance. They are reliable for applications even in chloride and sulfide environments because of the high chromium content present in them. With about 22% of chromium, they offer exceptional resistivity against corrosion. They are used in a range of industrial sectors. Some of the industries that use the Duplex Steel 2205 Flanges are Chemical processing industries, Oil and gas refining industries, Pulp & paper manufacturing industries, transport and storage industries. They are also used in various Marine environments and High chloride environments.
