Life of steel shot

　　Steel shot is a spherical particle made of special materials through special heat treatment. First, high-quality steel blocks are melted, and then high-pressure water is used to spray the molten steel into microparticles. The formed shot is reheated to purify and homogenize, and then quenched. The product features of steel shot introduced below: The quenched shot is dried and reheated in the furnace to achieve the applicable hardness. The tempered steel shot is sorted into different grades of products that meet SAE standards through a mechanical screen for use in shot peening equipment.

　　Moderate hardness, strong toughness, impact resistance, long service life, up to 2000-2900 times, good rebound, fast cleaning speed, low consumption, no breakage, fast cleaning speed, and good technical effect. The cleanliness of the metal surface treated by this product can reach GB/T8923-1989; the surface roughness reaches Rz=10--150μm, and the hardness can be increased to hrc57~62 when processing hard metal.

　　They have good toughness, service life is several times that of cast iron shot, and are widely used. The high-quality alloy steel sand of steel shot has high density, few defects, narrow particle size distribution range, good metallographic structure after heat treatment, excellent mechanical properties, greatly improved toughness, anti-crushing and anti-fatigue properties of steel shot, high reuse rate, low consumption, and significant economic benefits. Steel shot can be widely used in shot blasting cleaning of steel structure parts before painting, surface strengthening of mechanical parts, surface finishing and other operations

　　Thereby increasing the specific surface area of the metal surface and improving the surface adhesion of the paint after painting, with very significant economic benefits, it is currently the most advanced and ideal metal abrasive for shot blasting cleaning and strengthening at home and abroad.
