Provided is a stainless steel plate having superior galling resistance and press formability during press forming even using general-purpose stainless steel and using an extreme pressure additive, such as a non-chlorine-based additive, and low viscosity press oil. A stainless steel plate (10) includes, for example, plate shaped stainless steel (12). On one main surface of the stainless steel (12), a depression (12a) with a cross-sectional triangular shape is formed along a grain boundary exposed on a base surface of the stainless steel (12). A surface coating (14) is formed on the one main surface of the stainless steel (12), which contains the surface of the depression (12a). The surface film (14) is an oxide and/or a hydroxide with Fe and Cr as main components, and the surface film has a thickness of 0.1 - 3.0 µm. In addition, this surface film (14) contains an atomic percent of Cr of 10% or greater with the remainder being substantially Fe and has an oxide coating and/or hydroxide coating with a thickness of 0.1 - 3.0 µm. |
