In the paper the characteristic of the surface alloy layers on cast steel castings is presented. The assumptions for the simulation with the use of FLUENT software were worked out on the basis of the mechanisms known from the previous researches. The contact geometry (of preform and cast steel) and boundary conditions similar to the technological conditions were determined. The simulation was carried out for three pouring temperatures. The results of the simulations and the conclusions were presented. The real examinations for the same technological parameters were carried out to verify the calculations. The obtained results were compared.
