Abstract

PURPOSE: To produce a steel material having superior chemical treatability without deteriorating mechanical properties by ion-nitriding the surface of a steel material at a specified temp. to form an iron nitride-based nitride layer of a specified thickness on the surface of the steel material.
CONSTITUTION: The surface of a steel material is ion-nitrided at room temp. W700°C to form an iron nitride-based nitride layer of ≥100Å thickness on the surface of the steel material. When the steel material does not practically contain Cr, ion nitriding is desirably carried out at about 150W400°C. When the steel material contains 0.5W30wt.% Cr, the pref. ion nitriding temp. is about 350W600°C. The inferior chemical treatability of the steel material is improved without deteriorating the mechanical properties.
