A steel parts having an improved high wear and abrasion resistance is provided. The steel parts can be manufactured by a method wherein a steel parts containing 0.5 to 1.2 wt % of carbon is subjected to a chromium cementation treatment at a temperature of 1,000 to 1,100° C. with a cementing agent mainly consisting of carbide particles selected from the group consisting of Vanadium Carbide, Titanium Carbide, Niobium Carbide, Tungsten Carbide, Hafnium Carbide and Zirconium Carbide; metallic chromium and a sintering inhibitor to make an outermost surface of chromium carbide formed on the steel parts being dispersed with carbide particles selected from the group consisting of Vanadium Carbide, Titanium Carbide, Niobium Carbide, Tungsten Carbide, Hafnium Carbide and Zirconium Carbide. |
