Duplex steel flanges are made from work hardenable alloys that are exceptionally corrosion-resistant. A blend of austenite and ferrite phases makes up their composition. As a result, qualities of both austenitic and ferritic stainless steel can be found in duplex steel flanges. While duplex stainless steel is resistant to stress corrosion cracking, it is not as robust as ferritic stainless steel to this type of assault. The corrosion resistance of the least resistant duplex stainless steel, on the other hand, is higher than that of the most generally used stainless steel grades, 304 and 316. Duplex stainless steel is extremely corrosion resistant. They have high resistance to intergranular corrosion. Even in chloride and sulfide environments, Duplex steel flanges exhibit very high resistance to stress corrosion cracking. Duplex steel flanges are more resistant to saltwater than grade 316. It's nitrogen-enhanced stainless steel that was created to solve the 300 series stainless steel's corrosion resistance difficulties. Duplex steel flanges are frequently utilized in a variety of applications, including storage tanks, water heaters, and bridges. They are mostly used in situations when the austenitic grades might fail prematurely. Other applications include chemical processing, transport and storage, Oil and gas exploration and offshore rigs, Oil and gas refining, Pollution control equipment, Pulp & paper manufacturing, and Chemical process plant
