| Abstract: | High strength steel is still the main material of automobiles，and has certain advantages and potentials in light weight，energy saving，emission reduction and cost for automobiles. The use ratio of high strength steel increases year by year and develops towards higher strength. Lower cost are important developing trend，the low cost production modes mainly reflected in hot rolling instead of cold rolling to produce sheet steel，and cold forming instead of hot stamping to produce ultra-high strength automobile parts，and so on. The third generation automobile steel，which relies on the metastable austenite enhancing strength and ductility，has become important development trends of advanced high strength steel. The development of advanced automobile steels bring new challenges to the material science，processing and equipment. |
