Difference between alloy steel shot and stainless steel shot

August 05, 2024

Alloy steel shot and stainless steel shot are two different materials, the main difference lies in their composition, characteristics and application areas. Here are their main differences:

### Composition

- **Alloy steel shot**: Usually composed of iron (Fe) and other alloying elements such as carbon, manganese, chromium, nickel, etc. The addition of alloying elements can change the properties of steel, such as increasing hardness, wear resistance or corrosion resistance.

- **Stainless steel shot**: Mainly composed of iron and at least 10.5% chromium (Cr), sometimes containing other elements such as nickel, molybdenum, titanium, etc. This alloy gives the steel excellent corrosion resistance, especially to salt water, acidic and alkaline environments.

### Performance

- **Alloy steel shot**: Depending on its alloy composition, it can have a variety of properties, including high hardness, high wear resistance, good toughness, and specific heat or corrosion resistance. They are widely used in metal surface treatment, deburring, cleaning, polishing and other fields.

- **Stainless steel shot**: Due to its unique alloy structure, it has extremely high corrosion resistance and oxidation resistance. They are particularly useful in applications that require long-term exposure to harsh environments, such as chemical, food processing, marine engineering and other fields.

### Application fields

- **Alloy steel shot** is widely used, from automobile manufacturing, aerospace to mechanical processing, electronics industry, and almost all industries that require metal surface treatment.

- **Stainless steel shot** is mainly used for metal surface treatment that requires anti-corrosion protection, especially in the fields of food, medicine, chemical industry, etc., which have strict requirements on the corrosiveness of materials.

### Conclusion

Alloy steel shot and stainless steel shot have significant differences in composition, performance and application. Which type of steel shot to choose depends on the specific application requirements, such as whether to improve wear resistance, corrosion resistance or other special properties.
