Super Duplex Steel Plate Flanges are metal pipe flanges made from stainless steel alloy, including ferritic and austenitic components. They are superior to normal duplex steel plate flanges for their exceptional strength, corrosion resistance, and superior mechanical properties. Their higher Chromium and Molybdenum content gives them greater resistance to pitting corrosion, stress-corrosion cracking (SCC), general corrosion and cracking due to chloride ions present in seawater or acidic media. In addition, a 2-3x increased yield strength compared to standard stainless steels such as 304L/316L makes this material very suitable for applications with high pressure. ASTM A182 Super Duplex Steel Plate Flanges are widely used in industries like oil gas, petrochemical plants, chemical processing, water treatment systems, desalination, etc. They offer excellent formability under cutting conditions and low price points, making them an attractive option.
