duplex uns s31803 stainless steel pipe
Technically, the microstructure of a duplex 2205 tube is approximately 50% ferrite and 50% austenite. As a result, the properties inherited from both categories make this nitrogen-enhanced duplex 2205 seamless pipe ideal for use in industries such as food processing, oilfield piping and heat exchangers, and flue gas desulfurization.
ASME SA 790 UNS S31803 pipe also has improved mechanical properties such as higher yield strength, which is almost twice that of conventional austenitic stainless steel alloys. Meanwhile, ASTM A790 UNS S31803 is the specification for duplex steel materials. The material is a steel alloy that contains chromium and molybdenum. The addition of these materials makes the pipe stronger and more resistant to corrosion. SA 790 UNS S31803 is one of the super duplex grades, offering higher strength and corrosion resistance. Duplex grades are divided into three groups namely Duplex, Lean and Super Duplex.
