The comparison of steel shot and steel grit production process

　　Production technology of steel shot

　　A high quality steel block is melted, and the molten steel is formed into a fine particle by high-pressure water injection. The resulting pellets are reheated to purify and homogenize, and then quenched. The quenched pellets are dried and reheated in the furnace to achieve the applicable hardness. The tempered pellets are sorted through a mechanical screen into SAE grade products for use in shot peening equipment.

　　The excellent heat treatment control process gives the best elasticity and fatigue resistance of the steel shot. Different size and hardness of the steel shot are suitable for different processes.

　　Production technology of steel sand

　　The raw material of steel sand is not the same as that of steel shot. It is mainly scrap material of high carbon steel or alloy steel. The waste steel material after heating and quenching is put into the crusher for crushing, and the semi-finished steel sand is obtained. Then the steel sand semi-finished products are screened and classified, that is, finished steel sand is produced. The waste steel material after heating and quenching can also be put into the crusher for crushing, and the semi-finished steel sand can be obtained and then the semi-finished steel sand can be screened and classified, that is, the finished steel sand can be produced.

　　The raw materials and production process of steel shot and steel sand are different, which also determines the difference between them and the use environment. The steel shot side is of better quality than the steel sand and has better durability. At the time of use can be based on the difference between the two to make a choice.
