- Steel shot and grit are used for:
- auto- and manual blasting of metal products (castings, forgings, steel constructions, pipelines);
- shot-peening of heavy-loaded parts (shafts, carriage springs, springs, cog-wheels) ;
- ragging (pinch-pass rolling) of rolls in rolling mills;
- as a filling of casting moulds in foundry;
- as a reinforcing constituent of composite materials ;
- boring of wells;
- biological protection in nuclear power engineering;
- metal surface cleaning before painting;
- descaling of steam-boilers;
- surface treatment of stone, granite-, marble- and natural stone-cutting;
- cleaning of cutting tools;
- surface preparation of parts for galvanic coatings, enameling;
- surface preparation of oil and gas pipelines for multi-layer coatings;
- cleaning of oil-storages and reservoirs.
