1. Content of alloy elements.

Generally speaking, steel containing 10.5% chromium is not easy to rust. The higher the content of chromium and nickel, the better the corrosion resistance. For example, the content of nickel in 304 material is 8-10%, and the content of chromium is 18-20%. Such stainless steel will not rust in general.

2. The training process of the manufacturer will also affect the corrosion resistance of stainless steel.

Large stainless steel plants with good training skills, advanced equipment and advanced technology can ensure the operation of alloy elements, impurities removal and billet cooling temperature. Therefore, the product quality is stable and reliable, with good internal quality and is not easy to rust. On the contrary, some small steel plants are backward in equipment and technology. In the process of training, impurities cannot be removed and the products will inevitably rust.

3. The external environment and dry and well ventilated environment are not easy to rust.

However, the environment with high humidity, continuous rainy climate or high pH in the air is easy to rust. 304 stainless steel, if the surrounding environment is too poor, it will rust.
