Description

STEEL GRIT tends to clean a little quicker than shot but breaks down at a faster rate. It is essential that media is kept in a moisture free environment, otherwise it may solidify. Due to the risk of ferrous oxide contamination, steel shot or grits are not suited to certain applications. Surface corrosion may occur after treatment, therefore immediate coating or temporary protection is essential. Metallic abrasives are available in three different types; suitability depends on application. Call Airblast’s technical staff for abrasive to suit your need. STEEL SHOT is made from high carbon steel which is tempered to give durability and resistance to fracture, used both for peening and cleaning. Typical applications include metal improvement, stress relief, removal of heat treatment residue, mill scale, rust and paint and sand from castings. CHILLED IRON GRIT is a white iron structure which shatters on impact rather than wearing round. Being harder than steel it has a quicker cleaning action. If used in automatic machines it can be less cost effective than steel due to its breakdown rate. Automatic airless machines would also require more frequent spares exchange. Air driven machines are generally the most usual application for chilled iron grit due to their speed and flexibility. The grits are frequently used to etch structural steel and components prior to coating with paint, metal spray or plastics. Usage of chilled cast iron poses the same storage problems of oxidisation as other steel abrasives. *5 Kg bag shrink wrap non-return 1 pallet. Order from a bag to a lorry load.
