What is the difference between alloy steel shot and stainless steel shot?

　　In the field of metal processing and surface treatment, alloy steel shot and stainless steel shot are two common abrasives, each with unique characteristics and a wide range of application scenarios. This article will deeply discuss the differences between alloy steel shot and stainless steel shot in terms of composition, mechanical properties, price and application fields. We hope that our company's explanation can help everyone better understand and choose abrasives that suit their own needs.

　　1. Differences in ingredients

　　Alloy steel shot, as the name suggests, is made of alloy materials composed of a variety of metal elements, mainly including iron, carbon, chromium, nickel, cobalt and other alloy elements. The addition of these elements significantly improves the hardness, wear resistance and corrosion resistance of alloy steel shot, allowing it to adapt to more complex and harsh processing environments.

　　In contrast, stainless steel pellets are mainly composed of stainless metals such as chromium and nickel. These elements give stainless steel pellets excellent corrosion resistance. Stainless steel shot has a high internal tissue density, is durable, and can maintain stable performance in humid or corrosive environments.

　　2. Comparison of mechanical properties

　　Stainless steel pellets are more suitable for cleaning metal surfaces that are prone to rust, such as stainless steel, aluminum alloy, copper, etc., due to their softer characteristics. Stainless steel shot has good fluidity, which is conducive to circulation in the machine. It can accurately cover and treat the surface of the workpiece, and at the same time cover up surface defects such as scratches, bumps, etc., making the surface of the treated workpiece smooth, uniform and rust-free.

　　3. Price considerations

　　Due to the higher manufacturing cost of alloy steel shot, its price is usually more expensive than stainless steel shot. This is mainly due to the higher raw material cost, production process complexity and higher performance requirements of alloy steel shot. However, considering the long life and high performance of alloy steel shot, it is often more cost-effective in long-term use.

　　4. Application areas

　　Due to its excellent performance, alloy steel shot is widely used in surface treatment and strengthening processes in automobiles, ships, molds, castings, steel and other industries. Especially when processing workpieces with high hardness and complex surfaces, alloy steel shot is an indispensable tool. It can significantly improve the surface quality and mechanical properties of the workpiece and extend the service life of the workpiece.

　　Stainless steel shot plays an important role in the surface shot blasting treatment of aluminum alloy, zinc alloy and other non-ferrous metal castings and stainless steel castings due to its good corrosion resistance and environmental protection. In addition, stainless steel pellets are also widely used in medical equipment, food processing, cosmetics and other fields to ensure the cleanliness and safety of product surfaces.
