Duplex stainless steel pipe has a higher alloy content, and the austenite and ferrite phases each account for about half of the two-phase structure. Endows it with high strength and excellent corrosion resistance, but it also brings certain difficulties to its processing, production and organization control.

Following the trend of the development of duplex stainless steel, in recent years, the research of duplex stainless steel has continuously increased in China. The statistics of more than 1,000 papers and reports related to duplex stainless steel from CNKI between 2000 and 2014 found that there were only less than 10 articles in 2000, and the number of articles in 2001-2004 was 20-40 articles/year, 2005-2008 The number of documents per year is 40 to 60 articles per year. From 2009 to 2014, documents related to duplex stainless steel increased rapidly and remained stable at more than 100 articles per year.

With the deepening of the understanding of duplex stainless steel, the research of Chinese duplex stainless steelworkers has gradually deepened. In recent years, studies on the thermoplasticity of duplex stainless steel have been made in terms of thermoplasticity, harmful precipitation phases and N alloy element control. Phase research, research progress in three aspects of duplex stainless steel N alloying and control.
