Steel shot is a commonly used metal abrasive, primarily used in surface treatment, rust removal, and strengthening processes. Steel shot models are typically categorized based on parameters such as material, hardness, and size. Common steel shot models include G10, G14, G16, G18, G25, G40, G50, and G80, where the number represents the diameter range (in millimeters). For example, G10 indicates a shot diameter between 0.10-0.30mm, while G80 indicates a shot diameter between 0.80-1.20mm. Steel shot is primarily made of high-carbon steel, low-carbon steel, and stainless steel, with different materials suited to different surface treatment requirements. High-carbon steel shot has a high hardness and is suitable for high-strength rust removal and strengthening processes; low-carbon steel shot has excellent toughness and is suitable for surface treatment of precision components; and stainless steel shot, with its corrosion resistance, is suitable for applications requiring high surface cleanliness. The choice of steel shot should be based on a comprehensive consideration of the workpiece material, treatment process, and equipment requirements.
