Abstract

To provide a highly corrosion resistant steel having excellent corrosion resistance without reducing its mechanical properties and weldability caused by the surplus addition of corrosion resistance improving elements. (1) The highly corrosion resistant steel has a composition comprising, by mass, 0.01 to 3.0% Zn, 0.05 to 3.0% Cu and 0.05 to 6.0% Ni, and further comprising one or more kinds selected from 0.0005 to 0.0050% Ca, 0.0005 to 0.010% Mg and 0.0005 to 0.010% rare earth metals. (2) Regarding the highly corrosion resistant steel, the region to a depth of 500 μm from the outermost surface of the steel is provided with a Cu+Ni concentrated layer in which the content of Cu+the content of Ni are ≥1.2 times the content of Cu+the content of Ni in the steel and are also≥1.0 mass%, and the thickness of the concentrated layer is≥1μm. (3) In the highly corrosion resistant steel, the average ferrite crystal grain size in the specified region of the surface layer part in the steel sheet is ≤5 μm.
