Wear Resistant Steel Ball For Shott Or Peen Blasting Purpose
Product Descriptions:
Steel Shot is a spherical pellet made by special heat treatment of special material, which melts high quality steel and then sprays it with high pressure water to form molten steel into fine particles. The formed pellet is reheated to purify Homogenized, then quenched. Quenched pellets are dried and reheated in a furnace to achieve a suitable hardness. Temper-treated steel pellets are classified by mechanical screen into different grades according to SAE standards for shot peening equipment .
Excellent heat treatment control process gives the steel ball the best flexibility and fatigue resistance, different particle size and hardness of steel shot for different processes, such as is widely used in large quantities and heavy parts or materials such as shot peening.
Steel shots are widely used for descaling and descaling pre-painted steel workpieces, in which case centrifugal shot blasting equipment is often used. Ball shape and hardness of the small steel balls will not produce greater wear and tear on the device.
Steel balls are also widely used in sand casting.
When used with the right equipment, steel balls are the best abrasive for surface cleaning because they are durable.
