Duplex steel lap joint flanges are made from a combination of austenite and ferritic stainless steel, typically containing 22-25% chromium, 4-7% nickel and 2-3% molybdenum. This material provides excellent corrosion resistance especially in high chloride environments. Technically these flanges provide high tensile strength, good fatigue resistance and improved toughness making them ideal for high pressure applications. Advantages of Duplex Steel Lap Joint Flanges include the flexibility to installation reduced installation time cost savings from no need for precision installation. They are also corrosion resistant perfect for processing and other applications.
