Abstract

Disclosed is a stainless steel member with a high corrosion resistance suitable for a structural member used in highly corrosive environments, such as an edge seal plate of a molten carbonate fuel cell. This stainless steel member includes a base material consisting of stainless steel containing chromium, and a corrosion-protective layer formed on the surface of the base material. In this corrosion-protective layer, a granular heterophase containing chromium is precipitated in an ordered alloy consisting of aluminum and the constituent elements of the base material.
