Basics About Los Angeles Steel Grit

By Essie Osborn


Steel grit refers to particles of steel used for a variety of applications either as peening or abrasive media. They are created from steel shot with the key difference lying in the size and shape of the granules. They are manufactured from crushed steel shot which leaves them smaller in bulk. The edges are sharp and have some broken parts. Manufacturers say it is tougher than shot although the hardness might vary from one kind to another.

Advanced technology has made it easy to customize this product to great extends. In Los Angeles steel grit comes in three main categories, that is GP, GL, and GH. GP category is the softest of the other two. It has a round external form which is shaped using steel water. It is strengthened using special techniques to make it hard and strong with high elasticity and fatigue resistance.

GL is harder compared to GP and similar to GP, it loses the distinctive sharp edges at the time of production because of shot blasting. It works best when used to prepare surfaces to be painted and in descaling process. GH has angular edges and is the hardest of all. This category creates smooth even surfaces when employed on surface treatment. Recommendation requires that it be employed only in wheel equipment mostly with high pressure air blasting devices.

Beginners find it challenging to select the correct commodity to buy when they want to achieve elegant surface preparation and treatment. This writing presents some fundamental points to keep in mind when selecting. Most vital aspects to think about are hardness, size, and shape. Level of hardness picked must base on nature of dirt or surface being prepared and the propulsion speed during application. Harder particles also cost more, hence that should also be a consideration.

Hardness in this commodity implies that it is able to resist deformation upon collision with the surface it is propelled at. The hardness must be balanced well with brittleness in order to reduce breakages during work. Tough pellets as compared to soft ones have higher cleaning rate and hence saves people time. The toughness of the chosen pellets should however be determined by the surface.

The size is the other important factor to consider when buying grit. Larger particles are able to give higher impact than smaller ones. Manufacturers grade the pellets in a way that they are all of same size to ensure uniformity of results. In case of a mixture, pellet size remains significantly the same.

This commodity has wide and varied applications. The main ones are blasting, peening, and cutting. When employed as a blasting media it eliminates contaminants on a broad range of substrates and surfaces. It imparts compressive power for loading metallic components like automotive springs, jet engine turbine blades, and heavy appliance crankshafts in peening applications. In cutting applications, pellets are utilized in gang.

Manufacturers perform various tests on their productions to ensure that their performance is optimal. Some of the tests include spectrographic and metallographic analysis, variable durability test, micro hardness testing, and particle fatigue testing and many others. Without these tests it would be hard to determine performance.
