Abstract Fe-Cr-Si alloys material has good abrasion resistance, corrosion resistance and high-temperature oxidation resistance, especially the introduction of Si element can further improve its corrosion resistance. In this work, two Fe-Cr-Si alloys with different Si (10wt. % and 12wt. %) contents were designed and prepared by an arc furnace process. The microstructure and corrosion resistance of Fe-Cr-Si alloys were investigated. Results has shown that the Fe-Cr-Si alloys are composed of primary dendrite and interdendrite matrix, and metal silicide Fe3Si formed in the microstructure. Fe-Cr-Si alloys have a wider passivation interval than 2Cr13 stainless steel and the corrosion resistance of the Fe-Cr-Si alloys increased by more than 20 times in 10%HCl solution compare to 2Cr13 stainless steel.\
