How to distinguish steel shot by hardness?

　　There are many kinds of steel shot. When using them, we can only use them reasonably if we clearly distinguish them. Specific splits can be distinguished by hardness

　　Steel shot is an ideal abrasive product. In the sand cleaning process of many castings, steel shot has a good sand cleaning effect. Steel shots are also widely used in descaling and rust removal of steel workpieces before painting.

　　Steel shots with different hardness have different uses. The hardness of steel pellets is generally HRC 40 ~ 50, and processing some harder metals can increase the hardness to HRC 57 ~ 62. Good toughness, service life several times that of cast iron pellets, wide range of applications.

　　Do you know how to distinguish between steel shot and hardness?

　　The hardness of cast iron shot is HRC 58~65. The hardness of this kind of steel shot is very high, so it is very brittle when frozen, and it is easy to break. It doesn't last long. It is mainly used where high shot peening intensity is required. The hardness of the glass ball is lower than the first two, and it is mainly used in occasions where iron pollution is not allowed, such as stainless steel, titanium, aluminum, and magnesium. It can also be used for secondary treatment after steel shot peening to remove iron pollution and reduce the surface roughness of parts.
