Abstract: The paper presents results of experiments carried out on industrial melts. There has been tested the REM influence on carbon properties (0.20%C) as well as austenitic cast steel Cr-Ni 18/8+Ti type. It was found that REM cause an essential improvement of cast steels impact strength and in case of austenitic cast steel - also the corrosion resistance improvement in boiling 65%HNO3 (Huey test).
