Case-hardened steel article

This case-hardened steel article is provided with a base metal and a carburizing layer, wherein the base metal has a predetermined chemical composition. The number density of Ti-based precipitates having a circle-equivalent diameter of 5-50 nm in a surface layer region from the surface to a depth of 0.1 mm is at least 0.5 precipitates per μm 2 . The number density of AlN having a circle-equivalent diameter of 50 nm to 100 nm in said surface layer region does not exceed 0.5 AlN per μm 2 .
