The anti rust stainless steel ball refers to a steel ball with stronger rust and corrosion resistance, and has the characteristics of easy welding and excellent polishing property, and is more suitable for industries with high surface requirements. The anti rust stainless steel ball is usually produced by a forging process. At present, the commonly used stainless steel ball is made of 201, 302, 304, 316, 316L, 420, 440C.
From the structural analysis, the anti rust stainless steel ball refers to a steel material which contains more than 12% of chromium and is therefore resistant to chemical substances. At present, the product is mainly used in medical equipment, food machinery, cosmetic accessories, body accessories, instrumentation and so on.
The anti rust stainless steel ball is not completely rust-free, but is not easy to rust. This is because a certain amount of chromium is added to the composition. With the addition of chromium, a dense layer of chromium oxide is formed on the surface of the steel, which can effectively block the re-contact of the steel with the air. Oxygen can't enter the steel, and it can prevent the steel from rusting.
