The internal quality of steel castings includes mechanical properties, internal defects, microstructure, chemical composition, and special properties.

Ordinary steel castings generally only require normal mechanical properties at room temperature. The more important steel castings should be inspected for internal defects, especially metallographic inspection, chemical analysis, and special performance inspection. Steel castings that work under special conditions should be inspected for the required special properties, such as high-temperature mechanical properties, low-temperature mechanical properties, fracture properties, and so on.

It should be pointed out that the terminal inspection of the quality of steel castings is only the last checkpoint to prevent unqualified steel castings from leaving the factory. The key to ensuring the quality of steel castings is to enhance the quality awareness of all employees within the enterprise, strengthen quality supervision and management over the entire production process of castings, stabilize the production process, organize safe production, and adopt advanced production technology and equipment, equipped with adequate and Effective inspection methods for process quality and casting quality.
