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.

Both these types have the properties of recyclability. Its recyclability usually ranges from 2000 up to 3000 cycles. And because of this high level of recyclability, these can generate lesser waste compared to other abrasive types which are expendable, thus, having a great impact to the environment. Another property of both is the hardness in which the levels usually ranges from 40 to 65.

These types of abrasive are used mostly in for industrial applications in the city Los Angeles, CA and 4 of the most common are surface preparation, shot peening, cleaning, and stone cutting. In application for cleaning, it is used to remove loose materials on metals surfaces. This application is often utilized in automotive industries for cylinder heads, for motor blocks, etc. In surface preparation, this includes the cleaning the surfaces which are covered with paint coatings, rust, dirt, or mill scale. Also for the modification of surfaces such as to create roughness so the paint and coating are applied better.

Grits are used to cut hard stones such as granite and these are used by multi blade large frames when cutting thinner and cutting smaller slices of blocks. Shot peening are processes for metal surfaces to strike it against hard shot particles. Peening may result to deforming the surfaces but it makes an improved metal durability.

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.
