How to choose steel shot to choose high quality steel shot

　　There are good quality and bad quality steel shot on the market, so what is the basis for everyone to choose? In fact, the quality of the steel shot can be identified based on its appearance, hardness, etc. Let’s take a look at it in detail below.

　　The primary key to identification is high quality. The performance quality identification of steel shot mainly involves appearance inspection, hardness measurement and fatigue life inspection:

　　1. Appearance identification of steel shot:

　　Standard steel shot is dark gray in color and has a certain brightness, giving people the impression that it is gray but not dull. This kind of steel shot makes people look more "mature". If it doesn't feel like this, then the quality of the steel shot is poor.

　　2. Identification of steel shot hardness:

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

　　3. Steel shot fatigue life:

　　Fatigue life is the ability of steel shot (sand) to resist breakage when it acts on the working surface. The abrasive with the longest fatigue life will be the most economical abrasive if it can transfer the appropriate amount of energy into cleaning. No matter which application field, the quality of steel shot and steel grit 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 your processing costs.

　　4. Identification of hollow steel shot:

　　According to the density, first calculate the density of ordinary solid steel shot, and then measure the mass and volume of the steel shot to compare the density. If it is smaller than the solid steel shot, it will be empty.
