The comparative advantages of alloy steel shot and cast steel shot

　　Alloy steel shot is a shot cut from steel wire, which is divided into stainless steel shot and ordinary high carbon alloy steel shot and low carbon alloy steel shot according to the difference of steel wire. Generally speaking, its lifespan is 3000~3500 times, which means that it can be recycled so many times. In fact, there is no scrapping standard. During the cycle, it will slowly wear out and become dust. It is very versatile and can be used for almost any surface treatment of workpieces. Because of its long service life, it is deeply loved by customers, and the market is very good, and the dosage is also large, especially in some shipyards, mold industry, foundry industry, steel mills and other enterprises. Generally speaking, it has a 15-30% longer life than cast steel shot, because it has no pores and porosity, and has good organizational uniformity. It is mostly used for stainless steel and aluminum castings, because it will not pollute the castings after shot peening. And more wear-resistant. The high hardness strengthens the blades, cylinders and connecting rods used in aero-engines and diesel engines. Because of its bright appearance and no rust, it is widely used in the surface blasting treatment of high hardness workpieces such as automobile springs, suspension springs, quenched gears, screws, chains, various stamping parts, standard parts and stainless steel. After the workpiece has surface descaling, surface strengthening treatment and so on.

　　The cast steel shot is made of high-quality steel scrap, which is first melted, and then sprayed with high-pressure water to make the molten molten steel into small balls. The formed shot is reheated to purify and homogenize, and then quenched. The quenched shot body is dried in a furnace and reheated and tempered to achieve proper hardness. The tempered steel shot is sorted through a mechanical screen into 11 grades that meet the SAE standard for shot blasting equipment . Products with different particle sizes and hardnesses are used for different processes, such as surface strengthening. Suitable for a wide range of industries: aerospace industry, automotive industry, sandblasting/painter, consumer goods manufacturing, container manufacturing/repair, foundry, granite/stone cutting and shipbuilding and ship repair, brokerage, oil and gas pipelines, plant maintenance and metalworking.

　　The utilization rate of alloy steel shot is relatively high, so I want to introduce the advantages of alloy steel shot first:

　　1. Alloy steel shot has a bright appearance and will not rust: it can be applied to the surface blasting treatment of high hardness workpieces such as automobile springs, suspension springs, quenched gears, screws, chains, various stamping parts, standard parts and stainless steel. For the processed workpiece, it has surface descaling, surface strengthening treatment, etc.

　　2. Alloy steel shot has no pores and porosity, and has good organizational uniformity.

　　3. The service life is longer than that of other steel shot, it can be recycled 3000 to 3500 times, and the wear is not as fast as other steel shot during use, but it will slowly wear and become dust during the cycle.

　　Because of the above characteristics, its quality has a great advantage in the same type of products, so it can be used in almost any workpiece surface treatment, such as large shipyards, mold industries, foundries, iron and steel plants and other enterprises.
