This nitrided steel member is also characterized in that: the hardened layer has a thickness of 2-50 µm from the surface of the nitrided steel member; the diffusion layer extends to a depth of more than 100 µm from the surface of the nitrided steel member; and the hardness of the diffusion layer at a depth of 100 µm from the surface of the nitrided steel member is higher than the hardness at a depth of 2 mm from the surface of the nitrided steel member by 100 HV or more.

A method for producing a surface-hardened material, comprising: an immersion step of immersing an iron steel material having nitrogen attached in the form of a solid solution on the surface thereof in a melt containing a chloride at a temperature ranging from 650 to 900°C; and a cooling step of cooling the immersed iron steel material to a temperature equal to or lower than a martensitic transformation start temperature at a cooling rate equal to or higher than a lower critical cooling rare at which martensitic transformation starts.
The volume of an ammonia gas to be introduced is varied depending on a nitriding potential in a processing furnace which is calculated with a furnace nitriding potential calculation device and a desired nitriding potential while keeping the volume of an ammonia decomposition gas to be introduced at a certain level. In this manner, the nitriding potential in the processing furnace can be brought close to the desired nitriding potential.
