TSINGSHAN Research Institute

Since establishment, Tsingshan has always been regarding technological innovation as the key driving force of enterprise development. Tsingshan has established several research centers, such as Tsingtuo Research Institute, Guangqing Research Institute, Ruipu Special Steel Research Institute.

I. Talents and Elites: The Institute has more than 500 full-time employees, leaded by Dr. JIANG Laizhu as the president and industry experts as department heads and chief engineers. It has cooperated with universities such as Fudan University, Beijing Central Iron and Steel Research Institute, University of Science and Technology Beijing, Hefei General Machinery Research Institute, and Fuzhou University in industry research.

II. Focusing on R&D Guarantee: The Institute has accumulatively invested more than 50 million CNY in equipments and more than 63 million CNY in research & development, and has acquired more than 80 (sets of) analytical testing instruments for electronic probe analysis, metallographic analysis, salt spray test, mechanical analysis, and atomic absorption, etc.

III. Fruitful Achievements by Innovation: The Institute has more than 200 self-developed patents, and has undertaken two major technical research and industrialization projects in Fujian Province, and has led the compilation of the two group researches “Welded Austenitic Stainless Steel Tubes for Decoration" and "Group Standard for Cold-rolled Austenitic Stainless Steel Decorative Sheets”; the number of the newly developed product grades increases from 15 in 2015 to 39 in 2018, and the production output rises from 75,200 tons to 397,100 tons. The steelmaking and hot-rolled strips of 304 stainless steel have dropped from 2.69% and 3.70% in 2015 to 0.14% and 1.77% in 2018 respectively, the product quality has reached the domestic advanced level in the two areas of deep-drawn products and 8K panels. In 2018, the Institute launched the world's first high-nitrogen, high corrosion-resistant, high-strength nickel-saving austenitic stainless steel—304D, which is a major innovation following the RKEF+AOD process in the history of stainless steel development.



In November 2019, Tsingtuo Group Co., Ltd. launched the world's first high-strength nitrogen-containing austenitic stainless steel,08Cr19Mn6Ni3Cu2N (QN1803), which is highly recognized and praised by the consumers for its high strength and excellent corrosion resistance. It has been successfully applied in the six major areas including plates & strips, decorative welded pipes, steel wire rods, steel bars, and seamless tube billets, which is a great research result achieved by Tsingtuo Research Institute recently.

Under the guidance of the professional team of the Institute of Information Standardization of Metallurgical Industry, Tsingtuo Group Research Institute, together with Fujian Haili Technology Co., Ltd., Fujian Hongwang Industrial Co., Ltd., Guangdong Shuangxing New Material Group Co., Ltd., Foshan Taiyuda Steel Group Co., Ltd. , Jiangyin Xiangrui Stainless Steel Fine Wire Co., Ltd., Aozhan Industrial Co., Ltd., Zhejiang Dongming Stainless Steel Products, and Zhejiang Tsingshan Steel Pipe Co., Ltd. and other strategic partners in the industrial chain, prepared six product standards for high-strength nitrogen-containing austenitic stainless steel 08Cr19Mn6Ni3Cu2N (QN1803) steel plates and strips, decorative welded pipes, wire rods, steel bars, section steel and seamless tube blanks. Such standards have been adopted by the expert meeting of the Professional Standardization Technical Committee of China Iron and Steel Association, and passed the examination by the centralized management unit for technical standardization, and approved by the China Iron and Steel Industry Association as The Standard Groups.
