UNS S31803 tubes
What is UNS S31803 tubes?
The UNS S31803 material has 50-50 ferrite and austenitic microstructure. They show great resistance to stress corrosion in neutral chloride solution. The UNS S31803 Tubes can be suitably used in applications within the temperature range of -50 °F to 600 °F. They can also be used in applications beyond this temperature range, but there will be certain limitations, especially if it is an A790 UNS S31803 Welded Tube.
The seamless tubes have duplex microstructure with high strength and high resistance to corrosion. They are used in brewing tanks, hot water tanks, desalination plants, etc. The tubes are capable of handling high pressure devices.

What is SA 789 UNS S31803?
SA 789 UNS S31803 material has high nitrogen content which is why they show good resistance to pitting and crevice corrosion. The Duplex UNS S31803 Tubing should be used for applications taking place below 600 °F. They are resistant corrosion in both organic and inorganic acids, especially if they contain chlorides.
Exposure to elevated temperature for a prolonged period can reduce the toughness and corrosion resistance properties of UNS S31803. The ASTM A789 UNS S31803 Heat Exchanger Tubes are low weight and they can reduce the overall fabrication cost.
