All Grit Abrasive


Understanding steel grit blasting abrasives offer a significant advantage to an industrial contractor’s productivity and profitability.  If the steel grit you’re using is too hard, it may disintegrate on impact or cause damage to the blasting surface, while if it is too soft, it may disfigure in shape on impact and not be much use at all.  Both extremes are a waste of time and money.  Somewhere between these extremes is the optimal hardness. Contact us and one of our experts will help you decide.

Understanding Steel Grit Hardness
Hardness is a resistance of the metal to plastic deformation - usually by indentation.  This term may also refer to a metal’s stiffness.  This term may also refer to a metal’s stiffness, resistance to scratching, abrasion or cutting.

Types of Steel Grit
There are different grades, sizes and applications with steel grit.  BlastOne can help you decide which steel media is appropriate for your usage and indeed suggest which wheel machine or similar is most appropriate for your applications.

Chilled Iron Grit
Used for manual air-blasting.  It is made by quenching with cold water while red hot to produce a more brittle particle which will split on impact.  The additional particles hit the steel surface and thus increase blasting speed.  They will always maintain their sharp edges providing a speed increase of 8-12% compared with standard steel grit.  The angular shape gives a more consistent profile and superior coating adhesion.

GL Steel Grit
Loses it sharp edges during shot blasting and is best suited to descaling and surface preparation applications.

GH Steel Grit
Having maximum hardness, GH remains angular.  Mainly used in blastooms where working requirements take precedence over cost price considerations (eg - with rolling mill cylinders or when a special finish is required.)  Mainly used with air abrasive blasting in blastrooms.
