摘　　要：首先对中国汽车发展的现状与趋势进行了分析预测,2020年中国汽车产量可能达到3 600万辆。伴随汽车迅速发展的同时,汽车用钢也面临安全、环境、资源、能源及成本等方面的挑战。中国汽车的高速增长和庞大的市场为汽车用钢的发展带来重大机遇,同时冶金行业也面临来自非钢材料的激烈竞争和用户方面的挑战。就汽车用钢的发展潜力和钢铁行业可能采取的应对方案进行了讨论,分析了近年汽车用高强钢合金含量的发展、新型高强钢的组织性能精细控制及应用技术、超高强双相钢及新型淬火配分钢的精细组织、冷轧高强钢中的纳米粒子析出控制、热成形钢的工艺与组织性能以及先进高强钢的成形应用技术等。最后,举例介绍了汽车用钢供应商的先期介入(EVI)服务体系的加强与完善。Firstly, the current situation and development trend of China＆#39;s automobile industry were analyzed and predict-ed, the auto production is likely to reach around 36 million in 2020. With the rapid development of auto, automotive steels are also facing challenges such as safety, environment, resource, energy, cost, and so on. The rapid growth of auto and huge market in China bring great opportunities for the development of automotive steel, while the metallurgical industry is also facing fierce competition from the non-steel material and challenges of users. The development potential of automo-tive steels and the response options that may be taken by steel industries are discussed. The recent development of alloy content in high strength automotive steels, the fine control and application technology of microstructure and properties in new high strength steel, the fine microstructure of ultra-high strength dual phase steel and quenching-partitioning steel, the control of nanoparticle precipitation in cold rolled high strength steel, the process and microstructure and properties of hot stamped steel, the forming technology and application of advanced high strength steel were also analyzed. Finally, the strengthening and improvement of early vendor involvement （EVI） service system of automotive steel suppliers were intro-duced.
