Abstract Firstly, the current situation and development trend of China’s automobile industry were analyzed and predicted, 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 automotive 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 introduced.
