AUTOMOTIVE FUEL PIPELINE CONSTITUTED OF STAINLESS STEEL

摘要

Provided is a stainless steel automotive fuel pipe having a copper brazed part with excellent corrosion resistance. The fuel pipe is characterized in that a Cu-Ni brazing material containing 3 to 10% by weight of Ni is used as a copper brazing material for in-furnace brazing, and a nickel component of a diffusion layer positioned midway between a stainless-steel base material and the copper brazing material of a copper brazed part are in a state similar to that of the stainless-steel base material.
