DRIVE
July 20, 2016
An object of the invention is to provide an inexpensive automotive member and feed oil pipe, exhibiting excellent salt corrosion resistance. [0002] An automotive member or a feed oil pipe includes: a member made of a ferritic stainless steel containing, in mass%, at most 0.015% of C, at most 0.015% of N, 10.5% to 18.0% of Cr, 0.01% to 0.80% of Si, 0.01% to 0.80% of Mn, at most 0.050% of P, at most 0.010% of S, 0.010% to 0.100% of Al, and one or both of 0.03% to 0.30% of Ti and Nb; a metal fitting made of an aluminized stainless steel sheet, the metal fitting being attached to the member; and a gap structure defined between the member and the metal fitting, the gap structure being exposed to a chloride environment, where the metal fitting has an Al-plating weight per unit area of 20 g/mor more and 150 g/mor less on a surface corresponding to a gap of the gap structure, and surfaces of the metal fitting and the non-aluminized member other than the gap are coated with a cation electrodeposition coating film having a thickness of 5 µm to 35 µm.
