ABSTRACT:
A fuel tank for a motor vehicle is fabricated from an austenitic stainless steel sheet having elongation of 50% or more after fracture by a uniaxial stretching test with a work-hardening coefficient of 4000 N/mm2or a ferritic stainless steel sheet having elongation of 30% or more after fracture with Lankford value of 1.3 or more. The stainless steel sheets are reformed to a complicated shape of a fuel tank without work flaws such as cracks or break-down. Excellent corrosion-resistance of stainless steel itself is maintained in the fabricated fuel tank. Consequently, the proposed fuel tank is used without diffusion of gasoline to the open air over a long term.
