To provide a chemical polishing material for a ferroalloy material which can remove non-uniform portions such as burrs to form a uniform surface, and to provide a method for producing the polished ferroalloy material having the uniform surface by using the chemical polishing material and polishing/treating the surface efficiently, and the polished ferroalloy material having the uniform surface.

The chemical polishing material for the ferroalloy material consists of an acid aqueous solution containing 15-25 wt.% nitric acid, 4-25 wt.% phosphoric acid and 7-25 wt.% sulfuric acid and 40-60 wt.% water. The surface of the ferroalloy material, particularly, that of a low-alloy steel material such as chrome steel and chrome-molybdenum steel is polished by using the chemical polishing material to produce the polished ferroalloy material having the uniform surface.
