High strength steel, the best choice for application in the lightweight technology of automotive body is limited to be used due to the forming technique. The principle, characteristics and present research developments of the advanced forming processes such as hydroforming tech-nology, laser butt welding technology and hot stamping technology are discussed. And also the constitutive model of the advanced high strength steel is explained in order to provide the basis for improving the forming property of the steel.
