Steel shots have moderate hardness, strong toughness, impact resistance, longer service life and better cleaning speed. The important point is that they can be used repeatedly. Everyone in the abrasive industry knows that when the hardness of the steel shot is greater, the speed is very fast when cleaning the workpiece, but the consumption of the corresponding steel shot will also become faster, so its service life will be more than normal. Time shortens quickly. Therefore, generally from the perspective of economic benefits, generally, steel shots with moderate hardness are selected for processing before the workpiece is cleaned. As a metal abrasive, steel shot is widely used in machinery, aviation, casting, etc., for shot peening of major machinery and heavy parts or materials, descaling and rust removal before coating of steel workpieces, etc. , Steel shot is mainly used to clean the workpiece, the choice of steel shot is directly proportional to the work efficiency.
The correct choice of steel shot is the key to improving work efficiency. The hardness of steel shot is high, the cleaning effect of the workpiece is good, and the relative consumption is high. Therefore, when choosing steel shot, the material and hardness of the workpiece must be considered to improve the service life of steel shot. . The choice of steel shot is not a blind choice, and many factors need to be considered. Stainless steel shots are mainly used for surface shot blasting, sand blasting, shot blasting, shot peening, smoothing, strengthening, matting, correction, paint removal, and corrosion removal of stainless steel parts, aluminum alloy die castings, and copper alloy parts. Stainless steel shot has moderate hardness, pure ingredients and large coverage. Because it does not have the shortcomings of ordinary cast steel shots, such as pores and special shapes, its service life is longer. After stainless steel shots are treated, the surface of the castings is smooth and does not rust, and no pickling is required. Such post-treatment is beneficial to environmental protection.
