Recently, the world's highest-strength automobile wheel steel provided by TISCO has been successfully applied to new energy high-end models of well-known domestic and foreign automobile brands. The automobile wheel steel has passed the industry's material certification. In addition, after it was processed to make new wheels, the wheels passed more than 6 months of road test verification. After the first product review, TISCO's steel achieved the world's first launch of 1300 MPa warm-formed automobile wheel steel.

Against the backdrop of the rapid development of the global electric vehicle industry, the contradiction between the endurance of electric vehicles and the weight of the entire car has once become an important factor restricting the development of the industry. As a key component to ensure the safety and appearance of automobiles, the weight reduction technology of automobile wheels is the primary bottleneck that needs to be broken through. To this end, well-known domestic high-end wheel companies have proposed the goal of doubling the material strength. After learning the news, the TISCO technical research and development team immediately connected with relevant companies. Faced with the demand for high-strength and lightweight wheels for electric vehicles, the team rose to the challenge and fully mastered various technical quality indicators through in-depth communication and exchanges. The working team has overcome key technical difficulties such as smelting, continuous casting, and rolling. On the premise of ensuring the safety, lightweight, durability, and aesthetics of the wheels, it has achieved the phased goal of doubling the material strength and reducing the weight of the wheels and obtained two authorized patents. In terms of material forming and processing, compared with traditional hot-formed steel, the heating and cooling processes of 1300Mpa-level warm-formed wheel steel are more efficient, which not only greatly reduces energy consumption and improves efficiency, but also extends the service life of production equipment and effectively reduces process manufacturing costs.

In the process of tackling key technologies of this variety, the technical research and development team deeply implemented policy requirements, gave full play to the core driving role of scientific and technological innovation, and continuously promoted the research and development of original technologies, realizing the rapid innovation of automotive steel products, and contributing to the high-quality development of enterprises and the rapid development of the national automobile industry.
