Duplex 2205 and Super Duplex 2507 stainless steel flanges are characterized by their high yield strength, which is twice that of the annealed yield strength of typical austenitic stainless steels, like 304 and 316 stainless steel flanges. Because of this, Duplex 2205 and Super Duplex 2507 steel are some of the most common grades of duplex used for flanges with Super Duplex 2507 flanges being the more corrosion resistant grade of the two.
