Cast steel parts are metal components formed by casting steel through a casting process. They possess advantages such as high strength, good toughness, resistance to impact, wear resistance, and the ability to be customized with complex structures. Compared to cast iron parts, they have stronger load-bearing capacity and higher reliability. Compared to forged steel parts, they have lower costs and greater freedom in shaping. With excellent comprehensive mechanical properties, cast steel parts are widely used in various heavy industries, manufacturing, and infrastructure sectors, and are indispensable basic components in modern industrial equipment manufacturing. This article provides a detailed introduction to the main industrial fields where cast steel parts are applicable, helping enterprises make accurate material selections and rational applications.

Cast steel parts are widely used in heavy industry sectors such as metallurgy, mining, construction machinery, and power generation. These products have much higher strength, toughness, and wear resistance than ordinary cast iron parts. However, the casting process of cast steel is highly complex and sensitive, and defects such as pores, shrinkage cavities, cracks, slag inclusions, and deformation are prone to occur during the production process, which directly affects the quality and service life of the castings. To produce high-quality cast steel parts, it is necessary to strictly control all process details throughout the entire production process. This article thoroughly examines the details that need to be paid attention to in the casting process of cast steel parts, helping manufacturers improve the qualification rate of finished products.

During the casting, cooling and processing of steel castings, due to factors such as process, temperature and operation, various defects such as pores, slag inclusion, cracks, porosity and wear are prone to occur. Many enterprises directly scrap the castings when encountering defects, which significantly increases production costs. Some manufacturers also adopt improper repair methods, resulting in secondary damage to the castings and problems such as fracture and failure during use. In fact, most defects of steel castings can be repaired through processes to restore their performance. This article introduces effective repair methods for steel casting defects, helping enterprises reduce costs, increase efficiency and improve the utilization rate of castings.
