AUTOMOTIVE FUEL PIPELINE CONSTITUTED OF STAINLESS STEEL.

摘要

Provided is an automotive fuel pipeline constituted of stainless steel, the pipeline having a copper-brazed part that has excellent corrosion resistance. The fuel pipeline is characterized in that a Cu-Ni brazing material containing 3-10 wt% Ni was used as a copper brazing material for in-furnace brazing and that the nickel component of a diffusion layer in the copper-brazed part, the diffusion layer being located between the stainless-steel base and the copper brazing material, is in a state which is akin to that in the stainless-steel base.
