Steel production in Japan grew in tandem with the growth in domestic automobile production. Understandably, therefore, past development and expansion of the Japanese steel industry cannot be discussed without reference to the automotive industry of Japan. While the collision characteristics of a complete car body are ultimately evaluated through crash tests using real automobiles, to clarify the effects of individual improvement measures, it is necessary to examine the deformation behavior of the structure of the whole body prescribed parts and of the individual parts. While the crash energy absorbing property of frontal or rear collision by plastic deformation increases with increasing strength of the steel used, press formability improves with decreasing strength, and for this reason, steel sheets that are soft at the time of press forming and harden at the time of use, or those having strength highly dependent on strain rate, are desirable. However, the strain-rate dependence of steel strength decreases as the strength increases.
