Benefits and Features of Stainless Steel Super Duplex Flanges
The resultant metal comes with an enhanced metallurgical structure. It consists of two phases that benefit from the properties of both microstructures. These properties also make super duplex flanges highly popular in heavy industries like chemical processing, gas, nuclear, and oilfield service. Austenitic comes with lower resistance/strength to reduce stress corrosion cracking. Ferritic comes with poorer low-temperature toughness, poorer weldability, and lower strength. Producing a chemical composition can help combine ferritic and austenitic. This results in metal with resistance to stress corrosion cracking, good toughness, good weldability, and higher strength. The high strength of the duplex stainless steel flange means that the range of 0.2% PS for current duplex grades is from 400-500 MPa. It can lead to reduced section thickness and reduction in flange weight. The advantage of this is particularly significant for structural applications, such as bridges, storage tanks, a
