Shot (Steel Shot) is a spherical particle with a special material made of a special heat treatmentApplicable range of technologySurface preparation before coating, clear sand, pipe cleaning, strengtheningModerate hardness, toughness, impact resistance, long life, up to 2000-2900 times, good rebound, cleaning speed, low consumption, not broken, clean up fast, good technical results. After disposing of the product metal surface cleanliness of up to GB / T8923-1989; surface roughness of Rz = 10--150μm, thereby increasing the surface area of the metal surface than the surface to improve the surface adhesion of the coating after application, with a very significant economic benefits, is currently the most advanced, the best throw blasting abrasive and reinforcing metal rust.
