NPR [Negative Poisson's ratio] material is known as the "rubber band" in steel bars. It has the characteristics of anti-magnetization, corrosion resistance, high strength and high toughness. The group is widely used in mines, West-East Gas Pipeline, highways, water conservancy, cultural relics protection and other projects, and has broad market application prospects. The patent of NPR bolt steel material and its production method was developed by the team led by Academician Dr. He in 2014. Compared with the traditional PR material, the new material has both "strong" and "tough" characteristics, and the strength can reach 1,050 trillion. Pa, the elongation rate can reach 60%, and it has the characteristics of non-magnetism and resistance to strong magnetic field magnetization.
In terms of technology research and development, as the only production and research base for NPR new materials, NPR steel plates and long products in China, the company will give full play to its existing resources and product advantages, actively explore the research and development and market applications of NPR new materials, and realize new The expansion of material technology in clad steel plates, pipes, rails, and wire products provides effective solutions for many downstream areas of new materials. In terms of market production, the company continues to achieve large-scale production of NPR new materials by virtue of advanced production equipment and technological levels, and continuously improves product profitability and market competitiveness.
With the increasing demand for high-performance new materials in the fields of new energy vehicles, wind power generation, consumer electronics, aerospace, etc., the NPR new material market will usher in a new round of development opportunities and open up a new "blue ocean" market for the company.
