Title:

STAINLESS STEEL FUEL TANK FOR AUTOMOBILE

Document Type and Number:

WIPO Patent Application WO/2002/009964

Kind Code:

A1

Abstract:

A stainless steel fuel tank which uses, as a base material, an austenite stainless steel exhibiting an elongation at break of 50 % or more when formed through uniaxial tension and a work hardening rate of 4000 N/mm?2¿ or less, or a ferrite stainless steel exhibiting an elongation at break of 30 % or more when formed through uniaxial tension and a Lankford value (r-value) of 1.3 or more. The stainless steel fuel tank is free of a defect such as a fracture or break even when it has a complicated shape, since the above stainless steel has excellent formability, and thus the tank is free from the leak of a gasoline vapor over a long period of time due to the excellent resistance to corrosion which is inherent in stainless steel.
