The present study was made in an effort to make various tests on the electrolytic isolation of sulfide from steel and to examine the value of this procedure. Further experiments based on this procedure were made to ascertain the inherent properties and the occurrence of sulfide phases in low-carbon alloy steels. The results show that the Sodium Citrate method is applicable to the isolation of sulfides from steels containing Manganese, Vanadium, Niobium, Titanium and Zirconium. The Hydrochloric Acid method is suitable for the electrolysis of Chromium steels. The sulfide in Aluminum steel is decomposed by aqueous solutions and can not be isolated electrolytically. The microscopic examination of isolated residues is found to be effective as a method for revealing the three dimensional shapes of sulfides. Chemical and X-ray analyses of isolated sulfides indicated that the alloying elements in steels may be divided into three groups according to their sulfide forming tendencies as follows: (a) Zirconium, Titanium, Manganese and Niobium are strong sulfide formers. (b) Vanadium and Chromium are medium sulfide formers. (c) Cobalt, Nickel, Molybdenum, Tungsten and Silicon are weak ones.
