Cast Steel Grit

Hardness of GP steel grit is between 40HRC – 50HRC, with angular edges, is good abrasive medias for sandblasting. It is tempered from GH steel grit, angular grit. GP steel grit mainly used for pretreatment of steel plate, steel casting parts and descaling etc. Like steel grit GP10, steel grit GP12, steel grit GP14, steel grit GP16, steel grit GP18, especially used for pretreatment of heavy and thicker steel plate, steel hydraulic turbines, steel blowers, auto generators, rolling mills, blooming mills, cylinder blocks of automobile and tractor engines etc. Regarding steel grit GP25, steel grit GP40, steel grit GP50, steel grit GP80, steel grit GP120 are mainly used for surface treatment of steel sheet, smaller steel casting parts, cutting tools etc. Especially for shipbuilding, usually use steel grit GP18, steel grit GP25 for surface treatment before painting or galvanizing etc.
