The Industrial Applications Of Steel Shot And Steel Grit

By Carl Cooper


Abrasives are types of particles that are made of steel and are used as abrasives or as peening media. These are often divided into two different shapes which are the shot and the grit. These two shapes will be addressing different uses for industrial applications.

Most of the abrasives are made from steel compositions and are consist of high carbon. This high carbon is said to be the very best deal between the mechanical efficiency, durability, and properties. These abrasives have its most important properties which are the grain shape and size, cleanliness, hardness, and toughness. Los Angeles steel grit usually characterizes the grains with angular shapes that are predominant. These grains can be obtained through crushing the shots, thus, resulting to having some sharp edges and as well some broken sections. These have different hardness and sizes.

Steel shots are spherical grains made of molten steels. It is produced by using the granulation process or the atomization process. The grains also have different hardness and as well as the sizes. A shot is often utilized for a shots blasting machine.

These 2 type have both the properties of being recyclable. Usually, the recyclability property ranges from 2000 to 3000 cycles. And since the level of recyclability is high, it can generate much lesser waste if compared to some other types of abrasives that are expendable, and thus, it result to having good impact to environment. Another property for both is hardness where in the level ranges ranges from 40 up to 65.

In Los Angeles, CA, this type of abrasives are commonly utilized for applications in most industries such as for shots peening, stone cutting, surfaces preparation, and cleaning. When cleaning, it will remove the loose materials on the metals surfaces. This purpose is usually applied by automotive industries for the motor blocks, cylinder heads, etc. Surface preparation includes surface cleaning when it is covered with rust, mill scale, coatings, or dirt. Also used in modifying the surfaces like making it rough to better apply the coating and paint.

The grit is also used for cutting some hard stones like granite. These are utilized by using large frames that are multi blade to be able to cut the blocks into smaller and thinner slices. Shot peening is the process of striking the metal surfaces repeatedly through hard particles of shots. This process can deform the surfaces but can also improve durability of the metal.

Aside from surface preparation, shot peening, and cleaning, other applications also are utilized by many industries. Other applications may include renovation, repair, and other construction processes. There are two processes in which abrasives are used and these are the blasting and the machining.

Blasting is an operation where in an abrasive material is propelled forcibly against any surfaces which are under a high pressure. This is done either to roughen a smooth surface, or remove the contaminants in the surface, smoothen a rough surface, or shape a surface. The pressurized fluid will propel the material.

The operation of machining removes the material from work pieces using the small particles of an abrasive. Examples on this process are polishing, grinding, and honing. These may be expensive types of processes but its finishes are better and also its tolerance.
