What is the difference between steel sand, steel shot and steel wire cut shot?

　　Steel grit: Because it is formed by crushing steel shot, the shape of the product is water chestnut. Hitting the surface of steel parts can increase the roughness, which facilitates the later painting of some workpieces and improves the adhesion of the paint.

　　Steel shot: The product is round and spherical. It has a very good effect in removing scale and the surface of the shot product is smooth and delicate. However, the roughness is not as good as that produced by steel sand.

　　Steel wire shot cutting: The rust removal effect is very good when it is first put in, and it can increase the roughness. After rounding, the oxide scale removal effect is very good, and the roughness is slightly worse. In terms of product cost performance, it is better than steel sand and steel shot.

　　First of all, steel shot is a traditional rust removal and polishing material. It uses high-speed rotating steel shot to collide with the metal surface, causing friction and impact, thereby removing rust, burrs and scale from the metal surface. Steel shot has different surface shapes, some are granular and some are flake-shaped, so they are suitable for different types of metal surfaces. Steel shots have a long service life and are relatively low-priced, but care should be taken to avoid environmental pollution by steel shots during use.

　　Next is steel grit, which is a natural abrasive made from a high-aluminum material. Steel grit has large surface roughness and high hardness, and is suitable for removing rust, burrs and scale from metal surfaces. Steel grit has a short service life and needs to be replaced regularly. At the same time, attention should be paid to protecting the environment.

　　Finally, there is the steel wire shot, which is a new type of rust removal and polishing material made of a mixture of steel wire and abrasives. The surface of the steel wire shot is wire-shaped and has strong shearing force, which can easily remove rust, burrs and scale on the metal surface. At the same time, the service life of steel wire shot shot is relatively long and the cost is relatively low. The disadvantage of steel wire shot cutting is that the polishing effect is not as good as steel shot, but it is suitable for some special metal surfaces, such as large steel structures, bridges, etc.

　　To sum up, the three materials of steel shot, steel sand and steel wire cut shot have their own advantages and disadvantages and are suitable for different occasions. When selecting rust removal and polishing materials, comprehensive considerations need to be made based on the specific conditions of the metal surface as well as cost, environmental protection and other factors.
