Steel abrasive

Blasting agents are the while blasting (also grit blasting and shot peening ) used excipients.

As blasting agent, for example, shot, grit, steel shot, glass beads or wire clippings from chilled cast iron, cast steel or steel are used. According to BGR 500 (formerly VBG 48) " blasting work " is the use of silica sand as an abrasive inadmissible. As blasting agent both spherical and angular material will be used. Metallic and mineral substances are very common for the abrasive, while synthetic or plant are rarely applied. The mineral and synthetic abrasives individual grains almost always have a polygonal shape with sharp edges. Ceramic and glass beads set with their spherical shape this be the exception to the mineral abrasives include ceramic and glass beads and all varieties of corundum (aluminum oxide Al2O3). The synthetic abrasives include plastics, to the vegetable abrasives nutshells or cork. The grains of the metallic beam means may include a spherical ( also known as a shot or shot ), cylindrical ( wire bead ) or square or angular ( also called grit or gravel ) have the form.

Increasing importance gained lately dry ice ( CO2) in the form of pellets. Dry ice blasting has the advantage that it is non-abrasive and residue-free sublimated to gas, so that only the worn dirt must be discarded.
