Abstract

Abstract

In this paper, the microstructure, corrosion resistance and wear resistance of Fe-Si-Mn-C-Ti high-strength building steel with different titanium content were tested and analyzed. The results show that the addition of alloy element titanium is helpful to refine the internal structure and improve the corrosion resistance of the steel. With the increase of Ti content from 0 to 0.15%, the internal structure of the test steel is refined firstly and then coarsened, the corrosion potential firstly shifts to positive and then negative, the wear volume firstly decreases and then increase, the corrosion resistance and wear resistance increases firstly and then decreases. When 0.06% Ti is added, the corrosion potential of the steel is shifted forward by 91 mV, the wear volume decreases by 9×10⁻³ mm³, and the corrosion resistance is significantly improved. Fe-Si-Mn-C steel without titanium consists of matrix Fe and M₃C carbides. When the content of Ti is 0.02%–0.06%, the steel consists of matrix Fe, TiC and M₃C carbides. When the content of Ti is 0.15%, the steel consists of matrix Fe, TiC, TiN and M₃C carbides.
