Steel Shot blasting is the most widely used process for cleaning, stripping and improving a metal surface. The grade or size of steel shot will determine the ultimate finish achieved on the surface of the metal. The round ball shape of the steel shot produces a clean, smooth and polished surface through a peening action created by the acceleration of the Steel Shot. In a peening application, Steel Shot is also used to impart compressive strength to torque or load bearing metal parts such as crankshafts, engine turbine blades and heavy-duty springs.
Steel shot is actually a sphere-shaped form of steel casting. The shot is manufactured by pouring a molten mixture of premium grade steel scrap and select alloys through a series of water jets. On contact with the water, the molten metal is atomized, forming round particles in a controlled range of sizes. These particles then fall into a water tank, are then dried, screened by size, quenched and tempered in a unique heat-treating process. A process that assures ultimate control over the microstructure and hardness of the product, prior to a final screening.
