Steel Shot Abrasive Blasting for Polishing s460
Steel Grit G10, G12, G14, G16, G18, G25, G40, G50, G80,G120
Steel grits are angular in shape and are produced by crushing oversize steel shots and subsequently heat treated by tempering to get the required hardness and microstructure.
These intrinsic characteristics of the product enormously enhance the performance of the blasting for heavy descaling, deep descaling and surface preparations.
The angular shape and relative hardness of steel grit ensures rapid cleaning rates and excellent recyclability. With variations in hardness and size, steel grit can also be used for cutting granite and stones.

1.Hardness: GP / GL / GH steel grit
GP: HRC42-52
Newly made products with angular, the grit are gradually rounded off in use and its particularly suited for oxide skin pretreatment.
GL: HRC53-60
Harder than GP steel grit, also loses its sharp edges during shot basting and is particularly suited to surface preparation applications.
GH: HRC60-64
High hardness, sharp edges remain during operation, mainly used for compressed air shot blasting equipment.
2.Production Strength
Bonzer adopts Arc Furnace Smelting and Double Quenching technology, which guarantee its metal abrasives' chemical composition and high strength, high tenacity, long service life.
