High-chromium cast iron is widely used in key components of industries such as mining and metallurgy due to its excellent wear resistance. However, traditional high-chromium cast iron still faces issues of unstable wear resistance and casting defects in practical applications. This paper systematically analyzes the relationship between the microstructural characteristics and wear resistance of high-chromium cast iron, with a focus on discussing the optimization paths for its wear resistance through alloy composition adjustment and heat treatment processes. Combined with improvements in advanced casting techniques, effective methods for enhancing the wear resistance and casting quality of high-chromium cast iron are proposed, providing theoretical support and technical references for material selection and process design in related industries.
