Document Type and Number:
Japanese Patent JP3941762
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide low Cr, i.e. inexpensive ferritic stainless steel which solves the problem as for external corrosion resistance in a salt damage environment in the conventional technique on using ferritic stainless steel after working and welding into an automobile fuel tank, fuel pipe or the like.
SOLUTION: The Zn-containing paint coated ferritic stainless steel is obtained by coating ferritic stainless steel comprising alloy elements having the following specified composition with a Zn-containing paint. The specified composition comprises, by mass, ≤0.1% C, ≤1.0% Si, ≤1.5% Mn, ≤0.06% P, ≤0.03% S, ≤1.0% Al, 11 to 20% Cr and ≤0.04% N, also comprises 0.002 to 0.8% Nb and/or 0.01 to 1.0% Ti, and the balance Fe with inevitable impurities.
