What is S110 alloy steel shot?

　　Strictly speaking, there is no such name as "alloy steel shot" because all steel shots can be called alloy steel shots. According to the new national standards GB/T18838.3 "High Carbon Cast Steel Shot and Sand" and GB/T18838.4 "Low Carbon Steel Shot" implemented on September 1, 2008, there are only two formal steel shot names, one is high carbon steel shot and the other is low carbon steel shot. The rest are unprofessional gimmicks.

　　High carbon steel shot is more commonly used, and its production and sales volume is far greater than that of low carbon steel shot, accounting for more than 95% of the entire metal abrasive industry, so the steel shot and steel grit usually refer to high carbon steel shot and steel grit.

　　Low carbon steel shot is expressed as low carbon alone. Some manufacturers call low-carbon steel shots low-bainite steel shots, which is also a clever way of calling them. I think this name comes from the difference in the internal metallographic structure of the steel shots themselves. The internal metallographic structure of high-carbon steel shots is uniform tempered martensite, while that of low-carbon steel shots is bainite. Therefore, the various names of "jingle bells" on the market are just a sales technique. But remember, it is the basic responsibility of every practitioner to continuously improve the technical level of products, improve product quality, do their own part well, so as to promote the healthy development of the industry and better serve customers. Speaking of S110, S is the abbreviation of steel shots, which is the international general model of steel shots. It is converted into the domestic standard of φ0.3mm, expressed as ss0.3.
