There Are Three Main Factors Affecting Stainless Steel Corrosion

Oct. 21, 2020

One: the content of alloying elements, generally speaking, the content of chromium in 10.5% steel will not rust easily. The higher the content of chromium and nickel, the better the corrosion resistance. For example, the content of nickel in 304 Stainless Steel is 8-10%, and the content of chromium reaches 18-20%. Such stainless steel will not rust under normal circumstances.

Second: The smelting process of the manufacturer will also affect the corrosion resistance of stainless steel. A large Stainless Steel plant with good smelting technology, advanced equipment and advanced technology can guarantee the control of alloying elements, the removal of impurities, and the control of the cooling temperature of the billet, so the product quality is stable and reliable, the internal quality is good, and it is not easy to rust. On the contrary, some small steel mills have backward equipment and technology. During the smelting process, impurities cannot be removed, and the products produced will inevitably rust.

Third: the external environment, a dry and ventilated environment is not easy to rust. However, the air humidity is high, continuous rainy weather, or the environment with high pH in the air is easy to rust. 316 Stainless Steel, if the surrounding environment is too bad, it will rust.
