TYPES OF DUPLEX STEEL S31803 TUBES

duplex steel s31803 tubes are one of the most popular and widely used alloys in the world. they are renowned for their superior strength, durability and corrosion resistance. duplex steel s31803 is a duplex stainless steel containing 25% chromium and 7% nickel. it has a high strength to weight ratio and excellent corrosion resistance properties compared to austenitic stainless steels such as 304l and 316l. duplex steel s31803 tube has excellent pitting resistance due to its low carbon content, which helps to prevent pitting corrosion.

tubes are available in two forms, seamless and welded. seamless tubes are made without welding, while welded tubes have a weld along the length of the tube. both types have advantages depending on your application requirements, however seamless tubes are more widely used due to their higher strength to weight ratio and ability to withstand higher temperatures than welded tubes.
