Abstract：This study conducted a systematic review of relevant literature on rare earth (RE) corrosion-resistant steel in recent years， comprehensively elaborating on its research progress and significance. The research shows that integrating high-abundance lanthanum (La) and cerium (Ce) elements into the composition design and production development of plain carbon steel can not only fully utilize the metallurgical purification， microstructure refinement， and performance regulation functions of RE elements， but also overcome the shortcomings of traditional corrosion-resistant steel， such as high cost and large pollution from coating and anti-corrosion processes. The basic research results have confirmed the key role of RE elements in optimizing inclusions， enhancing interface strength， and improving rust layer products， and clarified the corrosion resistance mechanism of RE elements. The production practice indicates that by using the wire feeding method in the continuous casting mold， RE elements can be effectively added in the continuous casting process of ordinary carbon steel， successfully solving the problem of yield in traditional addition methods. The multi-dimensional performance evaluation shows that RE corrosion-resistant steel not only has the corrosion resistance of "preventing rust with rust"， but also has excellent low-temperature impact toughness and welding process adaptability， which can meet the usage requirements of most engineering scenarios. In addition， researchers have further realized the standardization and normalization production of RE corrosion-resistant products by gradually building a complete standard system， which helps to improve product quality and market competitiveness， and opens up a new and innovative and sustainable path for the efficient and balanced utilization of high-abundance La and Ce resources and the upgrading of steel products. This has far-reaching significance for promoting the coordinated development of China's steel industry and RE industry.
