Generally speaking, alloy steel balls are widely used in the casting industry. When used with appropriate equipment, it is more durable and an ideal abrasive. Then there will be some other similar products in this industry. Only the better things can know how good they are. Today, we will compare alloy steel shot with cast steel shot and analyze the differences between the two.
Alloy steel shot is a ball made by cutting steel wire, which is divided into stainless steel, ordinary high carbon, and low-carbon according to the different types of steel wire. Generally speaking, the lifespan of alloy steel shot is 3000~3500 times, which means it can be recycled so many times. In fact, there is no scrap standard, and it will gradually wear out and turn into dust during the recycling process. It has great applications and can be used for surface treatment of almost any workpiece. Due to its long service life, it is highly favored by customers, has a good market, and has a large consumption, especially in some shipbuilding, mold, casting, steel and other enterprises. Generally speaking, its service life is 15-30% longer than that of cast steel shot because it has no pores or air pockets, and the structural uniformity of alloy steel shot is better. Mainly used for stainless steel parts and aluminum castings, as shot peening does not contaminate the castings and is more wear-resistant. High hardness can strengthen the blades, cylinders, and connecting rods used in aviation and diesel engines. Due to its bright appearance and rust resistance, it is widely used for surface spraying treatment of high hardness workpieces such as automotive springs, suspension springs, quenched gears, screws, chains, various stamped parts, standard parts, stainless steel, etc. Perform surface descaling and surface strengthening treatment on the processed workpiece.
Steel shot is made from scrap steel, melted first, and then sprayed with high-pressure water to make the molten steel spherical. Heat the formed particles again for purification and homogenization, and then rapidly cool them. The quenched pellets are dried in the furnace, then heated and tempered to obtain the appropriate hardness. According to the standards of the American Society of Automotive Engineers, tempered steel shot is classified into 11 grades for mechanical screening in shot blasting equipment. Products with different particle sizes and hardness are used for different processes, such as surface strengthening. Suitable for: aviation industry, automotive industry, sandblasting companies, consumer goods manufacturing, container manufacturing, casting, granite cutting and shipbuilding and ship repair, intermediaries, oil and gas pipelines, factory maintenance and metal processing.
It is not difficult to see from the above introduction that the difference between alloy steel shot and cast steel shot is firstly due to the different casting processes, casting methods, and materials, resulting in significant differences in the products presented, as well as differences in service life, quality, and maintenance methods. Secondly, in terms of application. In contrast, its advantage over cast steel pellets is that it can be recycled and reused multiple times until it is consumed.

The above is the difference between alloy steel shot and cast steel shot. It has a wider range of uses than cast steel balls, a longer service life, and is less prone to rust and wear. But I believe many users have noticed some similarities in its applications, although the effects and purposes may differ.
