Duplex stainless steel seamless steel pipe

As a kind of high performance pipe material, duplex stainless steel seamless pipe plays a vital role in modern industry. Its unique biphase structure, the coexistence of austenite and ferrite, gives it excellent mechanical properties and corrosion resistance, so that it has been widely used in many fields. This paper will deeply discuss the preparation process, performance characteristics, application fields and future development trend of duplex stainless steel seamless pipe, in order to provide a valuable reference for practitioners in related fields.
