The analysis of regulatory documents on the chemical composition and level of mechanical properties of austenitic high-manganese steel 110G13L for turnouts is performed. Using mathematical methods of statistics, correlation dependencies of the influence of impact toughness values on the strength characteristics of the metal are obtained. It is established that the values of tensile strength σb and impact toughness ak are decisive factors for a set of strength-viscosity properties of castings made of steel 110G13L. The rational composition of the metal is substantiated, taking into account the manganese content (≈12%) and the ratio of manganese to carbon (10.56-13.60) for the production of metal castings of group I according to GOST 7370-98.
