AMASTEEL Shot is actually a sphere-shaped form of steel casting. Born of a process that was developed and patented by John F. Ervin in 1939, 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 atomised, forming round particles in a controlled range of sizes. These particles then fall into a water tank, are dried, screened by size, quenched and tempered in a unique heat treatment process. This process assures ultimate control over the microstructure and hardness of the product, prior to a final screening.
AMASTEEL shot has received more quality recognition awards than any other abrasive manufacturer in the world.
