The mechanical properties of metals will be affected by the composition of raw materials, process conditions, and heat treatment. Still, among the commonly used castings, there are four main attributes that are more important for users of large steel castings, namely strength, usage scenarios, hardness, and corrosion resistance.

When the product is processed, a small module is done simultaneously. The result of the quality inspection for the module is the product result of the casting. Some tests will directly damage the tested product. The result of non-destructive testing can be used to judge the quality of the casting. The process of testing, especially the hardness testing of castings, is a more important item.

1. The heat treatment of steel castings can be verified in heat treatment operations and surface depth analysis.

2. It can be determined whether the material has the desired properties.

3. It can effectively identify whether the materials used in castings meet the standards.

4. The cost and fast performance of castings can be determined.
