Shots and Grit Abrasive Blasting Media's

Achieve the right profile with efficient blasting media.

Should you use Chilled Iron Grit or Steel Grit in a Blast Room?

If the steel shot of steel grit youre using is too hard, it may disintegrate on impact or cause damage to the surface, while if its too soft, it may disfigure in shape, on impact, and not be much use at all. Both extremes are a waste of time , and of course a waste of money. Somewhere between these extremes is the optimum harness abrasive for your application.
 

What is Hardness?

Hardness is a resistance of metal to plasting deformation - usually by indentation. This term may also refer to a metals stiffness, resistance to scratching, abrasion or cutting etc. It is the property of a metal which gives it the ability to resist being permanently deformed, bent or broken when an external load is applied.
 

How is hardness measured?

The most common hardness test applied is the Rockwell Hardness Test, This test is a hardness measurement based on the overall increase in depth of impression as a pre-described load is applied to the surface of the metal.

TYPES OF SHOT AND GRIT ABRASIVE MEDIA

It is important to know the differences in blasting media, since different abrasive blasting media are required for different applications. Blasting media can be used for purposes such as cleaning, stripping, etching, strengthening and polishing. In addition to the media type, grit or mesh size is another factor to consider for your application. The final choice of media depends on the nature of the work required and on the blasting equipment that is employed.
