S31803 duplex steel is one of the grades from the 2205 duplex steel family. The letter “S” is the prefix of the ASME or American Society of Mechanical Engineers to specify the steel with the following numbers identifying the elements in it.

S31803 though part of the 2205 family, differs from many other grades depending on the different compositions. The more the chromium, the duplex becomes super duplex with a higher PREN or pitting resistance equivalent number. S31803 has less chromium and PREN number than 2205.

ASTM, or the American Society for Testing Materials, has specifications for steel and other materials. It starts with a letter like A for ferrous alloys, followed by unique sequential numbers. ASTM A 790 is a specification for duplex steel with consensus from manufacturers, fabricators, specifiers, distributors, and users.

A790 S31803 or ASME SA790 UNS S31803 is a ferrite and austenitic microstructure combination alloy to have both properties. Like the A number by ASTM, S is the prefix of ASME or American Society of Mechanical Engineers with four following numbers. It specifies the composition of chromium, nickel, molybdenum, and other elements.

Duplex SA 790 UNS S31803 Welded Pipe and UNS S32205 are both of the duplex 2205 family. Though most of the compositions between ASTM A790 S31803 and UNS S32205 are identical, there are slight differences. The nitrogen, molybdenum, and nickel of Duplex UNS S31803 Pipe are higher than 31803 slightly. Hence the differences between the two include the following, among others.

  • S32205 with excess nitrogen has more surface safety compared to UNS S31803
  • S32205, with more nickel and molybdenum than S31803 and hence also more potent

A790 UNS S31803 seamless pipe belonging to the 2205 duplex steel family with high chromium content has many advantages. A few of them include the following, among others.

  • Process both the chloride and sulfide ions without cracking as with many other conventional pipes and tubes
  • Possess high strength and superior corrosion resistance because of the high chromium and nickel content
  • With PREN higher than 304 and 316, steel is the first choice in many applications requiring high corrosion resistance pipes and tubes.
  • With double the yield strength of 316 and 317 is possible to make the walls thinner to reduce costs.

SA 790 UNS S31803 tubing is suitable for many applications in many verticals that require high strength and corrosion resistance. A few of the verticals include chemical industries, automobile components, heat generators, and boiler parts, Also with high corrosion resistance SA 790 tubes are best for seawater and marine environments.

UNS S31803 Welded tubing is workhorse grade duplex steel with strength and weldability properties. It is suitable for various production industries, from oil & gas refining to pollution control equipment. Also, for chemical processes plants that require corrosion cracking resistance from sulfide and chlorine ions.
