Hongxin steel pill, trustworthy! Welcome to the Hongxin official website

　　First of all, high quality steel blocks, filaments and steel scraps are melted, and then the molten steel is thrown into water by high-speed centrifugal forming with a centrifugal disk, so that the surface temperature of the steel shot drops sharply and the shot body is formed. This is a quenching. After one-time quenching, the shot body is dried and reheated in the furnace for tempering to achieve the applicable hardness. After tempering, the steel shot is sorted into different grades of products conforming to SAE standards through mechanical screen for shot peening equipment.

　　The excellent heat treatment control process gives the steel shot the best elasticity and fatigue resistance. The steel shot with different particle size and hardness is suitable for different processes, such as shot peening for large batch and heavy parts or materials.

 

　　Steel shot is widely used for descaling and derusting of steel parts before coating. In this case, centrifugal shot blasting equipment is often used. The shape of the ball and the smaller hardness make the steel ball not wear the equipment.

　　Steel shot is also widely used for sand cleaning of castings.

　　When used with appropriate equipment, steel shot is the best abrasive for surface cleaning because of its durability.

　　Applicable industrial scope
