Product Description
Stainless steel balls are not rust-proof, but not easy to rust. The principle is that by the addition of chromium, a dense chromium oxide layer is formed on the surface of the steel, which can effectively block the re-contact between the steel and the air, so that the oxygen in the air cannot enter the steel ball, thereby preventing The effect of steel balls rusting.
420 stainless steel ball has high hardness, good rust resistance, wear resistance, magnetism and low price. Can be oily or dry packaging.420 stainless steel balls are mostly used in products that require precision, hardness and rust prevention, such as stainless steel bearings, pulley slides, plastic bearings, petroleum accessories, valves, etc..
