On using the surface treated materials, properties such as corrosion resistance and mechanical properties depend on chemical composition of the surface layer, which are effected strongly by treatment condition and kinds of base metal. The resistance of pitting and Strees Corrosion Cracking (SCC) of SUS 304 in chloride solution was improved remarkably by using Chromize. Application of Cu/Ni composite plating on SUS 304 improved crevice corrosion and SCC. And Ni-Fe-Cr-Mo layer which was produced by diffuision heat treatment after Ni plating on high purity ferritic stainless steel prevented SCC. And resistance of local corrosion was improved by PVD, laser, metalspraying method.
