Various researches have recently been conducted on the depletion of fossil fuel and environmental regulation in the development of automobiles. In order to comply with environmental regulations, lightweight technology to reduce the weight of the vehicle body is essential for improving fuel economy. The crashworthiness and NVH performance of the vehicle must be satisfied at the same time in order to meet the safety and performance requirements for the passengers. For the crashworthiness, it is necessary to apply high strength steel. However, the formability of the high strength steel is low and the application of high strength steel to the car body is limited. Hot stamping is a technology that involves heating the steel sheet over austenite transformation temperature and directly quenching it in the cold mold. It can also secure crashworthiness, as well as formability for lightweight technology. In general, a car body part consisting of various reinforcement and joining technology is required, but one-piece parts were developed by applying hot stamping technology for weight reduction and strength enhancement. In order to achieve high strength, a specific cooling rate(35 °C/s) is required for martensitic transformation in hot stamping of high strength steel. In this study, the major variables of the hot stamping process, which are the initial temperature of the steel and the mold cooling rate, were measured. In addition, the integrated type side outer, which satisfied both weight reduction and crashworthiness, was developed by evaluating the crashworthiness through the drop impact test.
