Product Description

Wearable steel ball 7.938mm 9.525mm 10mm stainless steel beads

Stainless steel balls are usually produced by the stainless steel forging process. At this stage, the commonly used stainless steel balls are made of 201, 302, 304, 316, 316L, 420, and 440C.

Steel that contains more than 12.5% chromium and has high resistance to corrosion by chemical substances (acid, alkali, salt). Principle: The principle is that by the addition of chromium elements, a dense chromium oxide layer 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 production of the steel.
