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.

b) Production Strength: TAA adopts Arc Furnace Smelting and Double Quenching technology, which guarantee its metal abrasives' chemical composition and high strength, high tenacity, long service life.

c) Application: Blast cleaning: Used for blast cleaning of casting, die-casting, forging; sand removal of casting, steel plate, H type steel, steel structure. Rust removal: Rust removal of casting, forging, steel plate, H type steel, steel structure.

Shot peening: Shot peening of gear, heat treated parts.

Sand blasting: Sand blasting of profile steel, ship board, steel board, steel material, steel structure. Pre-treatment: Pre-treatment of surface, steel board, profile steel, steel structure, before painting or coating.

d) Packing: 25kg/bag, 40 bags per pallet or as required.
