Steel grit meet American SAE standard, have Moderate hardness, toughness, impact resistance, long lifetime, good elasticity and adhesion, low consumption, good technical effect. Steel grit application (1)Sandblasting for Shipbuilding With grit blasting, oxygenated surface of ship hull is descaled,then improved the coating quality. (2)Castings Surface Pre-treatment Steel grit can also be used for surface pre-treatment,cleaning and descaling for casting parts. (3)Bridge and Steel Construction Pre-treatment and descaling for metal surface,increasing coating quality and antisepsis ability. (4)Cleaning Blast cleaning, forging, casting deoxidization, cleaning H section steel, stainless steel structure. (5)Derusting Casting rust, forgings, rust removing, iron removal, steel derusting, h-steel derusting, steel structure derusting. (6)Reinforcement Heat treatment part shot shot strengthening, gear shot strengthening.
