After all, in addition to the performance, workmanship, brand and safety performance of the car, the cost of boron steel is higher, so it makes sense for these luxury cars to be expensive! However, with the increasing demand of all people for automobile safety performance and the stricter control of automobile safety inspection in the world, it has become a direction of safe development for civil automobiles to use boron steel to build their bodies!
Advantages of boron steel material:
Compared with ordinary steel, boron steel has the advantage of more uniform stress, which ensures that the frame made of boron steel will not bend at a certain section during collision, thus keeping the carriage in a reasonable space; Second, in the beating process, ordinary steel is easy to crack, while boron steel is less damaged; Third, when sharp objects such as electric drills drill holes in two kinds of steel, iron chips will be drilled in ordinary steel, and only the outer paint of boron steel will fall off.
The core technology of GOA body is the body structure with high strength cockpit and high impact energy absorption capacity. The GOA high-strength car body developed by Toyota adopts double-sided galvanized steel plates with high tension and high elasticity, and the advanced integral stamping process and welding process greatly improve the torsional stiffness of the car body.
