S31803 / S32205 Small Size 1/8 Inch Duplex Seamless Steel Tube
Duplex Stainless Steel Tube Description
Duplex stainless steel tubes offer superior corrosion resistance compared to conventional austenitic stainless steels, especially in chloride-containing environments.
Duplex stainless steel tubes offer a unique combination of properties that make them highly desirable for demanding applications where corrosion resistance, strength, and durability are essential. Their versatility and performance characteristics make them a preferred choice in various industries.
High Strength: Duplex stainless steel tubes have higher strength than austenitic stainless steels, allowing for thinner walls and lighter structures without compromising performance.
Impact Toughness: They also offer good impact toughness at low temperatures, making them suitable for a wide range of applications.
Duplex Stainless Steel Tube Application
Duplex stainless steel is a very useful metal that is used the world over. It gets its name from the fact that it consists of two different grades of metal.
Essentially, Duplex is a Fe-Ni-Cr alloy that has a two-phase ferritic-austenitic stainless-steel microstructure when it is at room temperature.
