The purpose of this paper is to report on the results of metallographic research into the quality of X15N27T3MR-VD steel wire (EP700-VD). The reason for the research was an oxidized zone with intergranular cracking which had been detected on the surface of the wire. To remove the defects, a variety of chemical methods were applied to the surface. As the research shows, after the chemical treatment methods such as winding springs, blowing them with corundum, etching in a mixture of HNO3 and HF, and electropolishing were applied to the surface, the defects were removed completely.
