ASME SA790 UNS S31803 Tubing is one of the standard for various duplex stainless steel standards under the SA790 specification. The duplex steels are one type of stainless steels that have ferritic and austenitic phases in their metallurgic microstructure. These have high corrosion resistance and strength or a combination of properties from the ferritic steel phase the austenitic steel phase. The ASTM A790 Duplex Steel Tube can be compared to the 904L grade in corrosion resistance but has double the strength of the austenitic grades. The duplex grades are also expensive than the austenitic or ferritic stainless steel grades. The most used of the duplex is the Duplex 2205 Pipe which are also known as the standard duplex grades.

There are super duplex and lean duplex grades which have high alloying contents, high corrosion resistance and high strength. The ASTM A789 Duplex Pipe contains carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, nitrogen, copper and other elements. It is the high chromium content in the range of 18% to 29% in various grades that provides the material with high corrosion resistance. There are ERW, seamless, welded and other types in production. The Duplex S31803 Welded Tube is made from strips, coils and sheets of the same grade of material and are welded from end to end. Welding of the duplex grades need special added filler materials, preheating and post weld heat treatments. These differ from grade to grade according to their chemical compositions. The applications also vary from grade to grade and the duplex steels are replacing a few high alloy materials because of the low cost compared to the high alloy prices.
