Improved materials are required for increasing the durability of sugar mills trash plates, considering their mechanical properties. The aim of this work was to obtain a gray cast iron, slightly alloyed with chromium, to raise the combined wear resistance. The gray alloy cast was proposed with 0,5% Cr and 0,1% Sn, with a high level of perlite, and the performance of its properties was compared with the other experimental alloys. Finally, it is demonstrated that the values of hardness and combined strength of the proposed alloy are adequate and guarantee an acceptable machinating, which makes this alloy an advantageous material in comparison with those currently used.
