The paper deals with the study of thermo-physical properties of selected real steel grade. The work is focused mainly on phase transition temperatures and heat capacities, particularly liquidus and solidus temperatures, eutectoid transition, alfa-gamma and magnetic transition. Different thermal analysis methods were used for obtaining of experimental data: “direct” thermal analysis (TA), Differential Thermal Analysis (DTA) and Differential Scanning Calorimetry (DSC). Theoretical study of analysed steel grades was performed using IDS SW (Solidification Analysis Package) and thermodynamic SW Thermo-Calc with database TCFE7. Experimental and theoretical data were compared and discussed.Keywords: thermal analysis, steel, solidus, liquidus, eutectoid transition, alfa-gamma and magnetic transition, heat capacity
