ASTM A789 S32205 DUPLEX Stainless Steel Tube
ASTM A789 S32205 is a specification for duplex stainless steel tubes. Duplex stainless steel is a type of stainless steel that contains both austenite and ferrite phases in its microstructure, providing a combination of excellent corrosion resistance and high strength.
S32205 is a specific grade within the duplex stainless steel family. It has a chemical composition that includes elements such as chromium, nickel, molybdenum, and nitrogen, which contribute to its corrosion resistance and mechanical properties.
ASTM A789 is the standard specification for seamless and welded duplex stainless steel tubes for general service. It covers tubes with various dimensions, including outer diameter, wall thickness, and length. The tubes are typically used in applications such as chemical processing, oil and gas, and desalination plants.
Overall, ASTM A789 S32205 duplex stainless steel tubes offer a good combination of corrosion resistance, high strength, and cost-effectiveness, making them suitable for a wide range of industrial applications.
The material composition includes chromium, molybdenum, nickel and other elements.
The UNS S32205 U Tube has 0.14% nitrogen minimum. The difference in grading applies to different application types. The material has 448MPa minimum yield strength and 621MPa minimum tensile strength. So the WNR 1.4462 Boiler Tube is stronger than the ordinary stainless steel.
The material is corrosion resistant against localized corrosion. It can operate at temperatures up to 150 degrees Celsius without chloride stress corrosion cracking.
