Service conditions of cast frogs of high-manganese steel are considered. The rate of frog failure in service for the reasons of reaching limit level of contact fatigue defects and higher wear is determined. The paper analyses the joint influence of carbon and phosphorus on development of service defects in frogs, made of high-manganese steel (12.4 - 12.8 wt-%). Equations of multiple regression are derived, that describe the interrelation between the content of carbon and phosphorus in 110G13L steel and the failure rate of frogs in service. Methods for improvement of the quality of 110G13L steel for railway frogs are determined. (VDEh)
