Jingye Group successfully produces high-strength automotive beam steel 750L-H-DZ1

Recently, the First Steelmaking Division of Jingye Group successfully produced high-strength automotive beam 750L-H-DZ1, marking a new breakthrough for the group in the field of high-end automotive steel. 750L-H-DZ1 beam steel has the characteristics of high strength, high toughness, excellent cold formability, and excellent weldability. It has high yield strength, good fatigue resistance, strong adaptability to bending, stamping, and rolling processing, high dimensional accuracy, and excellent surface quality. It can effectively reduce the weight of the vehicle body, improve the load capacity and operational safety of vehicles, and fully comply with the current trend of lightweight, high-end, and green development in the commercial vehicle industry.

In the production process, the technical team adheres to precise control throughout the entire process, adopting advanced technology routes such as converter steelmaking, external refining, and continuous casting billet quality control, strictly controlling the purity, composition stability, and rolling temperature curve of the molten steel. Through refined composition design and microalloying technology, ensure uniform internal structure and stable mechanical properties of steel. From smelting, continuous casting to precision rolling and inspection, efficient collaboration and precise parameter matching of each process ensure the smooth development of new products.

The successful development of high-end beam steel has further enriched the group's matrix of high-end products such as automotive beam steel, enhanced the group's core competitiveness and brand influence in the automotive steel market, and injected new momentum into the group's expansion of high-end customers, optimization of product structure, and realization of high-quality development.
