Title:
STAINLESS STEEL SHEET FOR AUTOMOBILE FUEL TANK
Document Type and Number:
Japanese Patent JP2002060973
Kind Code:
A
Abstract:

To provide a stainless steel sheet for an automobile fuel tank excellent in workability.

This stainless steel sheet for an automobile fuel tank is obtained by using an austenitic stainless steel sheet in which breaking elongation is ≥50%, and work hardening ratio is ≤4,000 N/mm2 when worked by uniaxial stretching or a ferritic stainless steel sheet in which breaking elongation is ≥30%, and Lankford value (r value) is ≥1.3 when worked by uniaxial stretching as base material and forming a resin film composed of a carboxyl group- containing urethane resin having an elastic modulus of 1,000 to 60,000 N/cm2 at 100°C, in which solid lubricant grains are dispersed in the ratio of 1 to 35 mass% on the surface of the base material. In this way, the corrosion resistance of stainless steel is made the most of, and the volatilization of stored gasoline can be prevented over a long period.
