       There are many classifications of steel shots. When you use them, you must distinguish them clearly and use them reasonably. The specific split can be distinguished by hardness. The following is the specific distinction. Please understand it in detail. Steel shots are an ideal type of abrasive product. In many sand castings, steel shots have a good cleaning effect. Steel shots are also commonly used in descaling and rust removal before coating of steel workpieces.
       There are many classifications of steel shots. According to the hardness of the manufactured steel shots, steel shots can be divided into steel shots, cast iron shots, glass shots, etc. Steel shots with different hardnesses have different uses. The hardness of steel shots is generally HRC40 ~ 50. Processing some hard metals can increase the hardness to HRC57 ~ 62. Their toughness and good service life are several times as wide as those of cast iron shots.
       The hardness of cast iron shot is HRC58 ~ 65. This kind of steel shot has high hardness, it is very brittle, very easy to break and short in life. It is not widely used. It is mainly used in places with high shot peening strength. The hardness of glass shots is lower than the first two types of hardness. It is mainly used for stainless steel, titanium, aluminum, magnesium, and other situations that do not allow iron pollution. It can also be used in the second treatment after steel shot peening to remove iron pollution and reduce the surface roughness of parts.
