WHAT’S STEEL GRIT
Steel Grit/Steel Shot is commonly used in airless applications since it is softer than aluminum oxide and doesn’t fracture as easily. It is also used in direct pressure applications where a heavy profile is needed. Steel shot is used for shot peening of ferrous materials.
Metalic abrasives are ideal for airless blasting and shot peening and they have a long life.
