When compared to Ferritic stainless-steel grades, Duplex Steel S31803 Flanges have much greater toughness and ductility. The corrosion resistance of a metal or alloy, like with all stainless steel grades, is primarily determined by the composition of the metal, in this case, Duplex steel. The presence of elements like chromium, molybdenum, and nitrogen is thought to be the most essential for resistance to chloride pitting and crevice corrosion. Duplex Steel S31803 Flanges have an increased range of corrosion resistance due to the addition of these components. As a result, it is recommended to employ this Duplex Steel S31803 Flanges in many applications since its corrosion resistance range is similar to that of austenitic stainless steel grades, i.e. from Type 304 or 316 to stainless steels with 6% molybdenum. Another reason we recommend choosing Duplex Steel S31803 Flanges is that they have excellent stress corrosion cracking resistance. Duplex Steel S31803 Flange has inherited this feature from the Ferritic side of the stainless steel. For common austenitic stainless steel grades such as Types 304 and 316, Stress Corrosion Cracking could be a concern in specific conditions such as humidity, increased temperature, or environments containing certain chemicals such as chlorides. As a result, Duplex Steel S31803 Flanges are frequently used in industries like oil and gas, petrochemicals, and marine.
