The precision steel ball has moderate hardness, toughness and impact resistance during the working process. It can be used repeatedly several times. It has long service life, good rebound, strong adhesion, fast cleaning speed, low sand consumption, no breakage, and high brightness of the workpiece. The technical effect is good, and the cleanliness of the metal surface treated by this product can reach the international standard. The surface roughness reaches 25--100um, which increases the contact surface of the metal surface, improves the adhesion of the surface of the smear, and strengthens the metal structure on the refined metal surface. It has very significant economic benefits and is an ideal cleaning spray at home and abroad. High quality materials for polishing, descaling and strengthening.
Precision steel balls are usually produced by forging process. At present, stainless steel balls are commonly used in 201, 302, 304, 316, 316L, 420, 440C. A steel that contains more than 12% chromium and is resistant to chemicals. Stainless steel does not rust, but is not easy to rust. The principle is that by adding chromium, a layer of dense tissue of chromium oxide is formed on the surface of the steel, which can effectively block the re-contact of the steel and the air, so that the oxygen in the air cannot enter the steel, thereby preventing the steel from being produced.
