Much industry developed with the development of civilization, and many people came to use cars all over the world. As for the development of the human, the balance is kept as far as natural environments enjoy it, but the balance is changed into global warming, depletion of the ozone layer. The improvement of the correspondence of technology to the global environment is an unavoidable situation these days. A high aim to 'reduce the discharge of the whole world by 50% by 2050' in greenhouse gas reduction target in No. 15 U.N. Framework Convention on Climate Change contracting party meeting (popular name COP15) is raised. As for vehicle developing, it is necessary to act on the problem to reduce discharge of CO2 with better collision safety and better vehicle function using lightweight technology. The application of high tensile materials is one of the methods to make the body of the car lightweight. In that method, develop a 980MPa grade super high tensile materials stamping process that has the merit of cold press and mass productivity, while dealing with the formability and accuracy control difficulty.
