The most commonly used type of sandblasting sand is white silica sand. Other materials, such as glass beads, aluminum oxide, silicon carbide and even crushed walnut seeds, are also used for sandblasting applications.

Removing stubborn rust from steel requires more than elbow grease and cleaners. Sandblasting is the most effective way to get rid of rust and reveal the pristine steel beneath. Operating a sandblaster requires finesse to ensure that the metal is not scratched or pitted in the rust-removal process.

Steel shot or grit is usually available at different hardness levels, ranging between 40 and 65 on the Rockwell scale (400 to 850 on the Vickers hardness scale).

You must not use materials such as silica sand, river sand, beach sand and other white sand for abrasive blasting. Doing so is an offence under Victorian health and safety legislation and may result in prosecution where large penalties can apply.

No, abrasives which contain more than 1% free silica are forbidden. In the past, blast cleaning operations were done with silica sand. The term sandblasting originates from those days.

The surface work hardening can however result in distortion. For this reason blast finishes should not be applied to stainless steel thinner than 0.4 mm. To avoid product distortion on thin sections, blasting on both sides should be considered.

Steel shot is spherical in shape. Steel grit is random and angular. Steel shot will provide a smoother surface than steel grit. Steel grit, given its’ shape, will etch or erode the surface.

Steel Shot Blasting Media A steel shot abrasive consists of small, spherical pellet-type projectiles that are often made from carbon steel. Steel shot is widely used in various sheet peening and polishing applications and typically provides a smoother, more polished surface than many other types of blasting media.

Sandblasting grit, which is also called blast media, comes in many other forms, including glass beads, aluminum oxide grit, ground glass, steel shot, bits of cut wire, copper and coal slag, silicon carbide grit and ground industrial gems. All of these types of blasting media are available in several sizes.

The most commonly used type of sandblasting sand is white silica sand. Other materials, such as glass beads, aluminum oxide, silicon carbide and even crushed walnut seeds, are also used for sandblasting applications.

Abrasive grit blasting, or sand blast cleaning, is a surface treatment process widely used in a variety of different industries with many diverse purposes. Abrasive blasting is the process by which an abrasive media is accelerated through a blasting nozzle by means of compressed air. The abrasive used varies based on the surface treatment required.

Silcia sand, sand containing a lot of the chemical compound called silicondioxide, is the type of sand most commonly used in sandblasting around the world. Sandblasting can remove old paint. Another piece of sandblasting equipment is called the blast cabinet, and it is essentially a medium-sized box that sandblasts items placed in it.
