Recently, Jingye Group successfully produced cold-rolled duplex steel 780DP-CS, further enriching the group's high-end cold-rolled steel product series and significantly enhancing the group's core competitiveness and brand influence in the high-end steel market.
The cold-rolled duplex steel 780DP-CS produced this time is a high-performance, high-value-added key steel focused on high-end manufacturing. It possesses excellent weldability, cold working performance, fatigue toughness, and impact resistance, with uniform composition and high dimensional accuracy. This steel grade is primarily used in key areas such as new energy vehicles, high-end passenger vehicles, and intelligent rail transit equipment.
Its production process has extremely high requirements for process control. In order to overcome the technical difficulties, the Second Steelmaking Division, together with the Group's Research Institute, Technology Research Center and hot rolling and cold rolling process units, formed a special task force to carry out in-depth collaborative process research and development and production debugging. By optimizing the smelting process, accurately controlling the content of alloy elements, refining the key parameters of rolling and heat treatment, and strictly implementing the quality inspection standards of the whole process, the team ensured that the mechanical properties and processing performance indicators of the products fully met the customized needs of customers and industry standards, and successfully achieved high-quality and stable mass production.
The successful production of cold-rolled duplex steel 780DP-CS is a concrete example of the company's customer-demand-oriented approach to transforming itself into a manufacturing service industry through product development and technological reform. This initiative not only effectively enhances the core competitiveness of the group's products and creates greater value for customers, but also helps achieve high-quality development in collaboration with the industry.
