Steel shot are steel grains made of hypereutectoid alloyed steel by original technology, which allows producing shot with maximum sphericity and provides it with optimal operating properties. That is, the technology of STEEL SHOT WORKS allows receiving the steel shot with stable sieving and best abrasive properties along with high durability. Thus according to the report of independent German laboratory the durability of our steel shot since the end of the year 2008 exceeds the nominal durability 2900 (+/-50) passes by 10-20 % according to the method Ervin Test, which corresponds 100% to SAE J445 K . The KNOW-HOW technology provides our steel abrasives with excellent abrasive properties due to high rigidity (resilience) of steel shot, which transfers the impact energy on the surface treated, but not on the deformation of abrasive particles. Big consumers in the German automotive industry have tested our steel shot and compared it to the abrasive material of Wheelabrator Allevard (WA). Our product has the index of Almen Test 110, the material of WA has the index of 91, which in practice provides the excellent quality of surface cleanliness while using our steel shot at that the intensity of cleaning is proportionally increased by 20%, which results in the economy of electricity, labour costs, shot-blasting machine life, expensive dust-filters etc.The attention should be paid that this advantage in the abrasive properties is achieved with almost equal hardness levels: the hardness of our steel shot is 473 HV, while the hardness of the WA steel shot is 487 HV. In other words we get not hard, but very rigid steel shot, which operates selectively: it doesnt damage the wearing parts of shot-blasting machine, but it cleans the surface perfectly.
