This paper presents influence of rare earth metals (REM) on the methanical properties, microstructure and morphology of non metallic inclusions as well as the cracking mechanism of G17CrMo5-5 high temperature cast steel. The research has been performed on successive industrial melts. It was found that non metallic inclusions the cracking mechanism of Charpy specimens and the impact strength were all changed. The following properties were tested: mechanical properties (R-m, R-e), plastic properties (A, Z), impact strength (S-Cl) and the K-JC stress intensity factor.
