How to choose steel shot to choose high-quality steel shot

　　There are good and bad steel shots on the market, so what do you choose based on? In fact, the quality of the steel shot can be identified based on the appearance and hardness of the steel shot. Let's take a closer look. The first key to identification is high quality. The performance quality identification of steel shots is mainly appearance inspection, hardness measurement and fatigue life detection:

　　1. Appearance identification of steel shot: The color of standard steel shot is dark gray with a certain brightness, which gives people the feeling of gray but not dim. This kind of steel shot makes people look more "mature". If it is not this feeling, then the quality of the steel shot is worse.

　　2. Identification of steel shot hardness: The hardness of steel shot determines the service life of steel shot. The hardness of steel shot is proportional to the cleaning speed. The higher the hardness, the faster the cleaning speed, the more steel shot is consumed, and the shorter the life. The manufacturing process of steel shot determines the size of steel shot. The larger the diameter, the higher the surface roughness after cleaning, but the work efficiency is also very high, and the wear is also greater relative to steel shot.

　　3. Fatigue life of steel shot: Fatigue life is the ability of steel shot (sand) to resist crushing when it acts on the working surface. The abrasive with the longest fatigue life will become the most economical abrasive if it can convert the appropriate energy into cleaning. Regardless of the application field, the quality of steel shot and steel grit is the key to effective operation. It determines whether the energy can be effectively converted during use, plays the role of cleaning and strengthening, and also determines the level of your processing cost.

　　4. Identification of hollow steel shot: First calculate the density of ordinary solid steel shot according to the density, then measure the mass and volume of the steel shot for density comparison. If it is less than the solid steel shot, it is empty.
