Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a metallic fuel tank for vehicle in which the low temperature embrittlement of a tank main body using a high-strength steel plate or a stainless steel plate can be prevented as much as possible. SOLUTION: An upper and a lower tank member 2, 3 which are each formed using a high-strength steel or a stainless steel plate are superposed on each other in the flanges 2a, 3a. The superposed flanges are joined together by seam welding and then annealed in the temperature range of 700-900°C. COPYRIGHT: (C)2007,JPO&INPIT |
