Steel abrasive comes in two types: steel shot and steel grit, which are used to remove rust, scale, and paint from surfaces. They can be projected by compressed air or centrifugal action. Steel abrasives are available in different grades, sizes, and hardness levels. Abrasive blasting can achieve various surface effects on materials such as glass, denim, and stainless steel. Steel abrasives are useful for heavy-duty applications, work hardening, and preparing surfaces for painting, polishing, or powder coating. Both types of steel abrasive can be applied in similar ways and have specific applications. Protective clothing and respirators should be worn during abrasive blasting.
Steel abrasive is a term generally applied to two types of steel abrasive media: steel shot and steel shot. These media come in the form of spherical or irregularly shaped grains or particles, which are projected at high speed against the surface of a workpiece to remove rust, scale or paint, to impart texture or even harden the surface. The abrasive particles of steel can be projected by means of a jet of compressed air at high pressure or by the centrifugal action of a spinning wheel or impeller. Steel abrasives of both types are available in a selection of grades defined by grit size, hardness and impurity levels.
Abrasive blasting is a technique used to achieve a wide range of surface effects on different materials such as stainless steel, glass and denim. Decorative finishes such as patterned glaze, simulated wear, and etching can be achieved by beading and sandblasting materials such as glass, plastics, and fabrics. Steel abrasive techniques using steel grit or steel grit are especially useful for heavier duty applications where they are used to remove surface imperfections, rust, dirt and scale from metal objects in preparation for painting, polishing or sanding. powder coating. Metal parts can also be work hardened by exposure to an abrasive action of steel known as shot peening. The same techniques can also be used in other areas such as the reconstruction of the road surface and the masonry or concrete finishes.
There are two basic types of steel abrasives, both featuring a selection of different grades and sizes. The first of these is the steel ball, which consists of spherical steel particles or grains. The second type is steel shot, which consists of angular or irregularly shaped steel grains. Both types have specific applications that they are particularly suited to, but can also be applied to a range of common applications. The application methods for both ball and grit are also similar.
In both cases, the grains are projected onto the work surface at high speed in two ways. The first is pressure blasting, which uses a powerful blast of compressed air to drive the abrasive into the steel. The second is a centrifugal action process in which the abrasives spin from rapidly rotating discs or impellers. Both of these processes are often performed in specially designed booths which collect grit or sand for further use, facilitate dust collection and contain much of the noise generated. Abrasive blasting operators should also wear protective clothing and respirators to ensure safety at all times.
The grade varieties for both types of steel abrasive take into account the levels of impurities, such as oxides, in the steel. Common sizes for both types include grain sizes between 0.007 and 0.1 inch (0.2 and 2.5 mm). Steel grit tends to be harder than shot peening, with average values for both in the range of 40 to 65 on the Rockwell scale.
