[0002] Steel shot is a spherical particle made of special materials through special heat treatment. First, high-quality steel blocks, wire, and steel chips are melted. Then, the molten steel is thrown into water using a centrifugal disk at high speed to form a shot body, which causes the surface temperature of the steel shot to drop sharply. This is a quenching process. After the quenching process, the shot body is dried and reheated and tempered in the furnace to achieve the appropriate hardness. After tempering, the steel shot is sorted by mechanical screen into different grades that meet SAE standards for use in shot peening equipment.
