1. Composition: UNS S31803, also known as Duplex 2205, is a duplex stainless steel with a balanced microstructure consisting of approximately 50% austenite and 50% ferrite phases. Its chemical composition typically includes elements such as chromium (21-23%), nickel (4.5-6.5%), molybdenum (2.5-3.5%), and a low percentage of nitrogen (0.08-0.20%).
2. Corrosion Resistance: One of the most significant advantages of UNS S31803 Duplex Steel is its excellent corrosion resistance. It provides resistance to a wide range of corrosive environments, including chloride-rich and acidic conditions, making it suitable for applications in the chemical, petrochemical, and marine industries.
3. High Strength: Duplex steel possesses higher mechanical strength compared to standard austenitic stainless steels. This increased strength allows for the design of lighter and more compact structures while maintaining structural integrity.
4. Good Toughness: Duplex stainless steel offers good toughness and ductility, even at low temperatures. This makes it suitable for applications in cryogenic environments.
5. Weldability: UNS S31803 is weldable using various common welding techniques, such as shielded metal arc welding, gas tungsten arc welding, and gas metal arc welding. This weldability makes it a preferred choice for fabricators.
6. Heat Resistance: While not as heat-resistant as austenitic stainless steels, UNS S31803 performs well at moderately elevated temperatures, making it suitable for applications in heat exchangers and other high-temperature environments.
