How to identify the quality of steel shot?

　　How to identify the quality of steel shot from its appearance? How should you choose products? Its function is one of the factors that affects our use results. Therefore, when we choose a product, we must pay attention to its product quality and learn to identify the quality of steel shot. So what exactly should be done? Next, let’s take a brief look at it.

　　Steel shot is used in the process of shot peening and blasting, so there are some quality problems during use, which requires us to put forward a requirement. Usually the evaluation of its performance and quality is mainly through appearance inspection, hardness inspection and fatigue life inspection.

　　1. Density identification

　　Based on density, we can first calculate the density of a general entity, and then measure the mass and volume to compare the density. If it is smaller than a solid steel shot, it is hollow. Otherwise, this is a very good quality product that reduces our judgment workload.

　　2. Appearance identification

　　The standard color of steel shot is dark gray, which has a certain brightness and gives people the impression of gray but not dark. This product makes people feel "old". If it doesn't feel that way, it's of even worse quality.

　　3. Hardness identification

　　Its hardness determines its service life, and its hardness is directly proportional to the cleaning speed. The higher the hardness, the faster the cleaning speed, the greater the consumption, and the shorter the service life. Its manufacturing process determines different sizes. The larger the diameter, the higher the surface roughness after cleaning, but the higher the working efficiency, and the greater the wear. It is very important to select the steel shot suitable for the corresponding vehicle type.

　　4. Life loss

　　Fatigue life is the ability to resist extrusion when working on the surface of steel shot. Products with fatigue life are undoubtedly economical metal abrasives. No matter which application field it is in, its quality is the key to effective operation. It determines whether energy can be effectively converted during use, plays a role in cleaning and strengthening, and also determines the level of processing costs.
