In this study presents the analyse of chrome iron cast structure (as-cast condition) which are used in rugged conditions abrasion-percussive and high temperature. While producing the casts of chrome iron major influence has been preserve the structure of technological process parameters. The addition to Fe-C-Cr alloy Ni, Mo or Cu and then proper heat treatment leads to the improvement of functional and mechanical cast qualities. Then it is possible to develop high mechanical properties which are recommended by PN-EN12513. As can it be seen from the above research silicon is an adverse chemical element in this kind of alloy cast iron. However, the reason of cracks appearing in chrome iron casts are phosphorus eutectic microareas. When the compound of Si and P reach the critical point, described in PN-88/H-83144 outdated standard, the microareas might appear.
