In response to the more stringent accident regulations and regulations recently enacted, even stronger steel sheets are now required to be used. This will not only increase the safety in accidents, but also avoid the increase in body weight. The three main strength properties required for thin steel plates for body parts are: tensile hardness; bending resistance; and breaking strength. The mechanical properties and thickness of the material have different effects on these three strengths. The tensile stiffness depends on the Young's modulus; the bending resistance depends on the deformation resistance and thickness of the material; the breaking strength depends on the Young's modulus, deformation resistance, and thickness. In general, materials with high tensile strength are best at resisting deformation. From this, it can be seen that the use of a high-strength thin steel plate instead of an ordinary thin steel plate has not yet been improved in the stretch forming, but the bending resistance and the breaking strength can be improved at the same time. Therefore, components with high requirements for breaking strength and bending resistance, using high-strength thin steel plates instead of ordinary thin steel plates, can ensure that the thickness is reduced, opening up a new way to reduce the weight of the vehicle body without increasing the material cost. The high-strength steel sheets used in car bodies must also meet requirements such as stampability, weldability, corrosion resistance, and strength properties.

Production has an impact. Collision safety People are increasingly concerned about higher fuel efficiency, and the requirements for improving the protection of passengers in car accidents are becoming more and more demanding. The safety of vehicles can be divided into active safety (ie, preventing car crashes) and passive safety (ie, ensuring passenger safety in the event of a car accident). The latter is directly related to the sturdiness of the car body. The method adopted to improve the safety in car accidents is to make the structure of the engine box able to absorb the impact energy and make the car more sturdy to ensure the safety of passengers. As a measure against accidents, thicker steel plates are used on each side of the engine box to enhance the absorption of impact energy. In order to improve the frontal impact resistance, not only the side but also the vibration plate and other components are designed to absorb impact energy.
