As a blast cleaning medium, shot, grit or a mixture is used to remove various forms of surface contamination from a broad spectrum of steel or foundry products. In a peening application, AMASTEEL shot is used to impart compressive strength to torque or load bearing metal parts, such as jet engine turbine blades, automotive springs, gears, or heavy equipment crankshafts. As a cutting medium, hard AMASTEEL shot and grit is used in gang-saws to process granite blocks. In addition, the sharp angular form of grit makes it ideal for etching a textured surface on metal - thus enhancing its ability to bond paint, enamel, rubber or other coatings. As the leading international producer of cast steel abrasives, Ervin Inclustries'AMASTEEL trademark has become synonymous worldwide with product quality, reliability and customer support. We believe that is why Ervin AMASTEEL'S market Share continues to grow throughout the World. It also explains why our products continue to find broad and growing applications in such varied markets as automotive, aerospace, agriculture, construction, foundry, mining, railroad, shipyard, stone cutting, office machine, petrochemical and other major industries. Shot and Grit Ervin AMASTEEL comes in four forms: shot, grit, a blend of the two which we call AMAMIX and a Premium Stainless Steel Shot we call AMACAST. 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, 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-treated process. A process that assures ultimate control over the microstructure and hardness of the product, prior to a final screening. Grit is made by crushing the fully hardened shot, screening the resulting media and tempering it to a desired hardness. |

Although AMASTEEL abrasives are used in the production of a wide array of products, they have four primary applications.
