Abstract:
A fuel pipe which is inexpensive and is excellent in salt spray corrosion resistance, characterized by being comprised of a steel pipe member having as a material a ferritic stainless steel which contains, by mass %, C: 0.015% or less, Si: 0.01 to 0.50%, Mn: 0.01 to 0.50%, P: 0.050% or less, S: 0.010% or less, N: 0.015% or less, Al: 0.010 to 0.100%, and Cr: 13.0 to 18.0% and further, one or both of Ti: 0.03 to 0.30% and Nb: 0.03 to 0.30% and a metal fitting part, the metal fitting part and the steel pipe member having between them a crevice structure at the surface which the structure is exposed to a salt spray environment, an opening amount at a crevice part of the crevice structure being 0.2 mm or more, and an inside of the crevice part being coated by electrodeposition.
