What are the differences in the effects of Stainless Steel cutting wire shot when processing different materials?

Stainless steel cutting wire shot is widely used in various industrial surface treatment processes, such as shot peening, cleaning, deburring, surface strengthening, etc. In the process of processing different materials, the effect of steel shot will vary due to the differences in the characteristics of the materials. Different metals, alloys, ceramics, plastics and other materials also have their own characteristics in their reactions and adaptability to stainless steel cutting wire shot, which directly affects the cleaning effect, the surface quality of parts and subsequent processing technology.

1. Processing of steel materials

(1) Cleaning effect

Stainless steel cutting wire shot shows significant effect when cleaning the surface of steel materials. Since steel itself has high hardness and strength, stainless steel cutting wire shot can effectively remove surface oxide scale, rust, oil stains, dirt, etc., especially for parts that have been heat treated or welded, the cleaning effect is particularly significant. In addition, steel shot can also produce moderate plastic deformation on the surface of steel materials while removing dirt, thereby enhancing its surface hardness and improving surface roughness.

(2) Wear and protection

Steel materials have good wear resistance to stainless steel cutting steel shots, but during use, the steel shots may cause a certain degree of wear on the steel surface, especially on steel materials with higher hardness. In order to avoid excessive wear, it is usually necessary to control the spraying time and force to ensure the cleaning effect while avoiding excessive damage to the surface of the parts.

(3) Applicability

Steel materials are widely used in construction, automobiles, aviation and other fields. Stainless steel cutting steel shots can be widely used in the surface cleaning of different steel alloys in these fields. Especially in large steel structures, steel pipelines, automotive parts and other fields, its cleaning effect is obvious, which helps to improve the corrosion resistance and service life of the product.

2. Treatment of aluminum alloy materials

(1) Cleaning effect

Aluminum alloy materials are softer than steel, so stainless steel cutting steel shots need to be particularly careful when handling aluminum alloys. The high hardness of steel shots may cause dents or scratches on the surface of aluminum alloys. Therefore, in the surface cleaning process of aluminum alloys, steel shots with smaller particle sizes are usually selected, and the spraying pressure and time are reduced. Steel shots can effectively remove the oxide layer, dirt and processing residues on the surface of aluminum alloys, but excessive impact force may affect its surface flatness.

(2) Effect of surface treatment

Although stainless steel cutting shot can effectively remove some impurities on the surface of aluminum alloy, its strength and hardness may affect the surface finish of aluminum alloy, especially for precision aluminum alloy parts, such as parts in the aviation and automotive fields, which have extremely high surface quality requirements. Therefore, when processing aluminum alloy materials, it is necessary to carefully control the selection of shot, spraying time, and pressure to avoid excessive wear or damage to the material surface.

(3) Applicability

Aluminum alloy is widely used in aviation, automobiles, electronic equipment and other fields. Stainless steel cutting shot is mainly used to remove oxide layers and impurities when cleaning the surface of aluminum alloy. In these industries, careful control of the cleaning process is the key to ensuring the surface quality of aluminum alloy materials.

3. Treatment of copper alloys and other non-ferrous metals

(1) Cleaning effect

Copper and its alloys (such as brass, bronze, etc.) are generally soft and have good corrosion resistance. Therefore, when stainless steel cutting shot is used to treat the surface of copper alloy materials, it is necessary to pay attention to controlling the strength. Since the surface of copper alloy is relatively sensitive, the high hardness of the shot may cause surface scratches or damage. During the cleaning process, lower injection pressure and smaller particle size of cutting steel shot are usually used to avoid damaging the copper alloy surface.

(2) Enhanced corrosion resistance

The cleaning effect of the copper alloy surface is mainly reflected in the removal of oxides and dirt. Although steel shot can clean impurities on the surface, the impact force on the copper alloy is large, which can easily cause surface damage. In order to avoid the surface becoming rough or corroded, the cleaning operation must be extremely careful, and a more gentle cleaning method can be used when necessary.

(3) Applicability

Copper and copper alloys are widely used in electrical, electronic, and piping systems, especially in the manufacture of precision electronic devices, where high surface quality requirements are required. In these applications, when using stainless steel cutting steel shot to clean copper alloy, it must be ensured that no unnecessary damage or changes are caused to its surface.

4. Processing of ceramic and plastic materials

(1) Cleaning effect

Ceramic and plastic materials are more fragile than metal materials, and stainless steel cutting steel shot needs to be used with extreme caution on the surface of these materials. Ceramic materials are usually very hard and brittle, so if stainless steel cutting steel shot is used for cleaning, it may cause surface cracks or breakage, especially on harder ceramic surfaces. For plastic materials, although steel shot can remove surface impurities, excessive impact force may also cause cracking or deformation of the plastic surface.

(2) Surface damage

Due to the brittleness of ceramic and plastic materials, the hardness of stainless steel cutting steel shot is too high, which can easily cause irreversible damage to the surface of these materials. Therefore, when cleaning these materials, it is usually necessary to adopt a more gentle cleaning method, such as low-pressure spraying or using softer abrasives.

(3) Applicability

Ceramic and plastic materials are widely used in electronics, home appliances, decorations and other fields. The use of stainless steel cutting steel shot is limited for cleaning these brittle materials. Usually in these fields, cleaning methods that are more suitable for the characteristics of these materials are selected, such as airflow cleaning or chemical cleaning.

5. Summary

Stainless steel cutting steel shot, as a common surface treatment material, shows different effects in the surface cleaning of parts of different materials. For materials with higher hardness such as steel and aluminum alloy, steel shot can effectively remove surface impurities and improve surface quality, but on softer or fragile materials such as copper alloy, ceramic and plastic, steel shot may have adverse effects on their surface. In order to obtain the best cleaning effect, it is necessary to select the appropriate steel shot specifications, injection pressure and cleaning method according to the characteristics and requirements of different materials. In short, the reasonable use of stainless steel cutting steel shot can improve the surface treatment efficiency, but it is also necessary to adjust the use plan according to the specific needs of the material to ensure that the cleaning effect is achieved and the surface damage of the material is avoided.
