The similarities and differences in rail steel metallurgy between the USSR railroads and those in North America as explored in an FRA-Soviet Railway Ministry exchange program are discussed. Chemical and mechanical properties are compared for heat treated and non heat treated rails. To retard the rate of defect formation, USSR railways have adopted fully heat-treated rail as standard and the production process for these is illustrated. The plans for further rail steel research are described. Ultimately the aim is a steel with a 450 Brinnel hardness and 235,000 psi tensile strength by increasing carbon content and adding alloys such as boron and vanadium. Rail replacements in track are usually determined by defect formation rather than wear.
