Steel Shot Description:

Sphere-shaped form of steel casting used for blast cleaning to remove surface contamination in foundry products, in peening to impart compressive strength to torque or load-bearing metal parts and as a cutting medium for gang saws to process granite and marble. It 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, and then are dried, screened by size, quenched and tempered in a unique heat-treating process that assures ultimate control over the microstructure and hardness of the product, prior to final screening. It is available in 11 sizes.

Steel Grit Description:

is made by crushing fully hardened shot, screening the resulting media and tempering it to the desired hardness. Steel grit is ideal for aggressive cleaning applications and will quickly strip many types of surface contaminants from steel and other foundry metals. Because steel grit is softer than aluminum oxide and does not fracture as easily it is ideal for aircraft and aero-space applications. The angular nature of steel grit produces an etched surface on metal for superior adhesion of paint, epoxy, enamel, rubber and other coatings.
