I. Material and Performance Differences

Cast steel shot: Made from high-quality steel scrap, it has relatively low hardness, moderate wear resistance, and low cost.

Stainless steel shot: Made from stainless steel, it has high hardness, wear resistance, and good corrosion resistance.

Due to the differences in material and performance between these two abrasives, mixing them may lead to the following problems:

II. Problems with Mixed Use

Electrochemical Corrosion: Stainless steel shot has good corrosion resistance, while cast steel shot may contain impurities or alloying elements. When mixed with stainless steel shot, electrochemical corrosion may occur in humid or corrosive environments, leading to a decrease in abrasive performance.

Uneven Wear: Due to the different hardness of cast steel shot and stainless steel shot, mixing them may result in uneven wear, affecting shot blasting effect and equipment lifespan.

Affect on Shot Blasting Quality: Different abrasive materials have different effects on the shot blasting quality of the workpiece surface. Mixing them may lead to unstable shot blasting quality, failing to meet specific process requirements.

III. Application Scenarios

When selecting abrasives, the specific application and requirements should be considered. For example, stainless steel shot should be preferred for workpieces requiring high surface quality or corrosion resistance; while cast steel shot can be chosen for cost-sensitive or less demanding applications.

In summary, due to differences in material, performance, and application scenarios, mixing cast steel shot and stainless steel shot is not recommended. In practical applications, the appropriate abrasive type should be selected based on specific needs and process requirements.
