Similarities and differences between steel shot and cast steel shot in abrasive

In the manufacturing industry, steel shot, as a metal abrasive, plays a role in cleaning surfaces, preventing oxidation and removing rust in industries such as aviation industry, automobile industry, sandblasting, paint spraying, consumer goods manufacturing, container manufacturing, repair, and casting. For the workpiece, the service life is prolonged and the efficiency of the workpiece is improved. Liaoning Steel Wire Cut Shot

What is the difference between steel shot and cast steel shot? We analyze from the aspects of raw materials and manufacturing processes.

Steel shots are made of special materials through special heat treatment. First, high-quality steel blocks are melted, and then the molten steel is sprayed with high-pressure water to form particles. The formed shots are reheated to purify and homogenize, and then quenched. The quenched pellets are dried and reheated and tempered in the furnace to achieve the appropriate hardness. The tempered steel pellets are sorted through mechanical screens into different grades of products that meet the SAE standard for use in shot peening equipment .

Cast steel shots are made of high-quality steel scraps, which are first melted, and then the molten steel is formed into small spheres with high-pressure water jets. The formed pellets are heated again to purify and homogenize, and then quenched. The quenched pellets are dried in the furnace and reheated and tempered to achieve the appropriate hardness. The tempered steel pellets are sorted into 11 grades that meet the SAE standard through a mechanical screen for use in shot blasting equipment.

Both steel shots and cast steel shots are used for surface pretreatment of castings before spraying; sand cleaning of castings; pipe descaling, etc. It has important applications in the aviation industry, automobile industry, oil and gas pipelines, factory maintenance and metal processing.

It can be seen that the raw materials of steel shot and cast steel shot are a bit different, the manufacturing process is basically the same, and the scope of application is basically the same. The difference is that the hardness of the steel shot is higher, and when used on the same product, the life of the steel shot is relatively shorter.
