方大特钢牵头联合高校实施省级重点科研项目 攻关重卡弹簧扁钢关键材料技术

Group 1 - The project titled "Research on the Control of Bainite and Toughness Mechanism of Large Cross-section Niobium-Yttrium Composite Micro-alloyed Spring Flat Steel" has been officially listed as a key project under the Nanchang Innovation Development Joint Fund of the Jiangxi Provincial Natural Science Foundation, led by Fangda Special Steel and involving Jiangxi University of Science and Technology [1] - Spring flat steel is a core material for heavy truck suspension guide arms, directly impacting vehicle safety. The material must withstand extreme conditions, including heavy loads and temperatures as low as -40°C, necessitating high strength, high plasticity, and low-temperature impact resistance [1] - The project aims to address common technical bottlenecks in the industry, such as insufficient uniformity and poor hardenability in large cross-section spring flat steel, which typically exceeds 50mm in thickness and 100mm in width [1] Group 2 - Fangda Special Steel is a leading producer of spring flat steel and automotive leaf springs in China, and it serves as a "chain master" enterprise in the new materials industry chain in Nanchang. The company has a strong focus on the spring steel niche, supported by a professional R&D team and several high-level research platforms [2] - The successful development of key material technology for heavy truck spring flat steel is expected to create a core technology system with independent intellectual property rights, potentially overcoming critical technical bottlenecks in the industry and supporting the industrialization of new hot-rolled spring flat steel [2]
