Composition: Duplex stainless steel is a family of stainless steels that contain a balanced mixture of austenite and ferrite microstructures in their crystal lattice. The most common duplex stainless steel grades are classified under two main groups: the standard duplex (or lean duplex) and the super duplex. Typical alloying elements in duplex stainless steel include chromium, nickel, molybdenum, and nitrogen.
Corrosion Resistance: Duplex stainless steel pipes are highly resistant to corrosion, making them ideal for applications in aggressive environments, such as those containing chloride ions, seawater, and acidic solutions.
Strength and Toughness: These pipes offer a combination of high strength and toughness, which allows them to withstand both high-pressure conditions and impact loads.
Stress Corrosion Cracking (SCC) Resistance: Duplex stainless steel exhibits excellent resistance to stress corrosion cracking, a common issue in many industrial environments.
Pitting and Crevice Corrosion Resistance: They are also resistant to pitting and crevice corrosion, which are critical concerns in applications involving chloride-containing substances.
Temperature Resistance: Duplex stainless steel maintains its mechanical properties and corrosion resistance over a wide temperature range, making it suitable for both cryogenic and high-temperature applications.
Weldability: Duplex stainless steel is generally weldable, allowing for the fabrication of complex structures and pipelines.
Cost-Effective: Duplex stainless steel offers a cost-effective alternative to some other high-performance alloys, particularly in situations where corrosion resistance and strength are essential.
