Abstract

DC60 (20/05/45) This invention provides structural components for automobiles. that can show strength Flexibility and energy absorption performance are excellent, and moreover. It can cause weight reduction and structural components for pipe-formed vehicles. High tensile steel with material properties of strength The tensile elongation is not less than 1400 MPa and the elongation is not less than 5%, and there is also a closed cross-sectional structure as the arrangement of the cross-section. perpendicular to the direction of the longitudinal axis, the arrangement of the cross-section It is according to the representation <1> below, where a is the maximum length of such cross-section arrangement in the longitudinal direction, where b is its maximum length. in the direction perpendicular to that direction, where L is its circumferential length and where t is defined as the wall thickness of the steel pipe 0.65 less than or equal to b/a less than or equal to 0.75, 0.014 less than or equal to t/L less than or equal to 0.020 and rated, that is determined so that the longitudinal direction of the arrangement Sort the cross-sections of the track components. The structure corresponds to the direction. of the collision of the car body when structural components are attached to the car body.
