Method for manufacturing impact energy absorbing component, and impact energy absorbing component

Abstract

The present disclosure provides a method for manufacturing an impact energy absorbing component, and an impact energy absorbing component which achieve both high collision performance and excellent EA performance by local heating. A method for manufacturing an impact energy absorbing component is a method for manufacturing an impact energy absorbing component including a member formed by processing a steel plate, in which at least a part of a bent ridgeline generated by the processing is heated at a temperature of 600°° C. to an AC1 point. An impact energy absorbing component is an impact energy absorbing component including a member formed by processing a steel plate, in which at least a part of a bent ridgeline generated by the processing has a Vickers hardness equal to or lower than a Vickers hardness of each of flat surfaces constituting the impact energy absorbing component.
