sand blasting cast steel grit

Details of Steel Grit:

 

G10, G12, G14, G16, G18, G25, G40, G50, G80, G120

 

1. Hardness:  GP / GL / GH

    GP: HRC46-50

    Newly made products with angular, the grit are gradually rounded off in use and its particularly suited for oxide skin pretreatment.

    GL: HRC56-60

    Harder than GP steel grit, also loses its sharp edges during shot basting and is particularly suited to surface preparation applications. 
    GH: HRC63-65

    High hardness, sharp edges remain during operation, mainly used for compressed air shot blasting equipment.
