Duplex stainless steel is an alloy that displays properties of both austenitic and ferritic microstructures and with such a mixture have proven to be better than either of the two. In terms of chemistry, the duplex S31803 flanges are known for the increment it shows when it comes to the percentage of chromium elements. This increase is backed by a significant rise in molybdenum and a lower amount of nickel. The counterbalancing of chromium and nickel is the one responsible for imparting the flanges with excellent corrosion resistance properties while ensuring that they retain the quality of strength that is contributed by the latter. The incorporation of nitrogen is also a distinct chemical feature of the S31803 flanges and is responsible for improving its resistance against chemical corrosion.
Owing to its versatile physical structure coupled with its efficient chemical diversity, the duplex S31803 flanges are known to exhibit excellent strength and toughness. This tough nature of the flanges is responsible for enabling them to strengthen the system and also defend themselves against any kind of mechanical strain. This same stability is seen when they are faced with corrosive liquids and gases including several acids. This stability can be attributed to the corrosion resistance they expertly manifest against a broad range of corrosive agents, protecting themselves against pitted, crevice, and stress corrosion, without letting it affect its performance in any manner. This property has enabled them to be used in applications involving exposure to such liquids, which only broadens the spectrum of its usage.
