Topographic projections of the surfaces of ultimate strength and tensile yield strength, and impact toughness of austenitic manganese steels have been constructed. A comparative analysis of the topographic projections of the surfaces of ultimate strength and tensile yield strength, and impact toughness of manganese steels of the austenitic class with the structural diagram of manganese steels is carried out. A comparative analysis of the concentration range of steel 110G13L, with the content of manganese and carbon regulated by the standard of Ukraine, with the structural diagram of manganese steels has been carried out. The analysis of the quality of the metal (structure and properties) in a cast track made of steel 110G13L, on samples cut from the body of a serial track was carried out. It was found that the surfaces of the studied properties of manganese steels are represented by planes with an increase in property values with an increase in manganese content and a decrease in carbon, within the austenitic region of the structural diagram. It has been established that the concentration area of 110G13L steel, with the content of manganese and carbon regulated by the Ukrainian standard, is located on three structural zones of the structural diagram of manganese steels. It was found that dendritic inhomogeneity and microporosity are observed in the track casting. The level of properties determined by tests of samples cut from the track casting is less than the calculated level of the same properties, provided the steel has the same manganese and carbon composition. Casting defects (microporosity and dendritic segregation) cause a decrease in properties on the samples, compared to the calculated level of properties.
The average derating factor is 0.65. It is recommended to set the carbon content in 110G13L steel in the Ukrainian standard at the level from 0.95 to 1.25 %.
