In the presented work, new thermodynamic approach based on basic thermodynamics was used for calculation of the surface tension of steel. Surface tension was calculated for three steel grades and calculated values were compared with experimental values at 1550 °C. Thermodynamic properties, which are necessary for this thermodynamic approach of surface tension, were calculated using Thermo-Calc software with TCFE7 database.
