Dipping experiments of tool steel samples into molten aluminum are commonly used to study the thermal fatigue issues of steel dies/inserts in the casting industry. In this study, thermal fatigue cracking of standard H13 tool steel was analyzed through both finite element analysis (FEA) simulation and dipping experiments. The dipping process was simulated using a FEA code ProCAST<sup>®</sup>, where thermodynamic and mechanical material models were established for the simulation. Mechanical test data were further employed to calibrate the thermomechanical database. Thermal and stress analyses of the test specimen were conducted using the simulation results. A modified universal slopes method was employed to predict thermal fatigue life of the specimen. A dipping apparatus for thermal fatigue testing was built and actual dipping experiments were performed for validation. Charpy V-notch was added and an optimal set of testing conditions were developed to establish efficient testing.
