Product details

Grit blasting media GH Steel Grit GH12 used for surface pretreatment of automotive high strength gears


●Product Name: GH Steel Grit

Type: GH10, GH12, GH14, GH16, GH18, GH25, GH40, GH50, GH80, GH120

Size available: 2.5mm, 2.0mm, 1.7mm, 1.4mm, 1.2mm, 1.0mm, 0.7mm, 0.4mm, 0.3mm, 0.2mm


●Application for GH steel grit

GH steel grit is the hardest blasting media of abrasive, with the highest hardness, hardness is between 60HRC – 66HRC, the original hardness of material steels. 

GH steel grit is steel blasting media, mainly used for those steel articles which be with higher hardness, like stones, steel plate springs etc. Like steel grit GH12, steel grit GH14, steel grit GH16, steel grit GH18, steel grit GH25, mainly used for sandblasting and surface treatment of automotive high strength gears, spring plates, stones etc. It is rapidly efficiency in blasting treatment, but it is easier to be broken and crushed, in other words, its fatigue life is not better than GP steel grit and GL steel grit.
