When the surface of parts or workpieces interacts with steel balls, there are many factors that affect mechanical parts or workpieces. In general, it can be divided into two aspects: First, the composition, organization and performance of parts or workpieces materials itself, that is, internal factors; the second is external factors, including steel shot and medium (shot shot shot shotplane) , Environment, load, speed and temperature, etc., the performance of steel shot is one of the main external factors that determine the abrasion resistance of the material.
The wear performance of the steel ball is related to the mechanical properties of the steel pill (such as hardness, strength, etc.), the state, the state of binding, and its size, shape, and motion conditions, especially the angle of the steel shot after the natural break rate.
The hardness value of steel shot is an important factor that determines the wear of metal abrasives. It is practically used to determine the size of the metal abrasive wear.
