Abstract
A seawater-resistant stainless clad steel includes a cladding material made of stainless steel having a pitting index represented by Cr[mass %]+3.3Mo[mass %]+16N[mass %], of 35.0 or more and a microstructure in a surface portion thereof including, by area ratio, less than 2.0% of a σ phase, wherein dynamic friction coefficients in the rolling direction and in a direction at a right angle to the rolling direction determined in accordance with JIS K 7125 are both 0.05 or less.
