GH steel grit: this kind of steel with high hardness, will always maintain the edges and corners in the blasting operations, on the formation of the rules, hairy surface particularly effective. GH steel grit for shot blasting machine operations, consideration should be given priority in the construction price factors required occasions (such as cold rolling mill roll processing). This steel is mainly used for compressed air equipment. Steel is mainly applicable to the blasting room, mainly is suitable for the roller, chain, hook type, crawler, by type, rotary, accumulating, stepping, trolley type shot blasting machine (shot blasting machine), shot blasting machine, shot blasting cleaning equipment, shot blasting machine, shot blasting, spray, sand blasting machine, shot peening equipment sand blasting equipment, derusting equipment, steel pretreatment production line equipment, steel pretreatment production line, steel structure pretreatment production line, sand house.
