What kind of stainless steel does not rust easily?

  There are three main factors influencing stainless steel corrosion:

  1. Content of alloy elements. Generally speaking, the content of chromium in steel at 10.5% is not easy to rust. The higher the content of chrome nickel is, the better its anti-corrosion property. For example, the content of 304 material nickel is 8-10%, and the content of chromium is 18-20%. Such stainless steel will not rust under normal circumstances.

  2. The smelting process of production enterprises will also affect the corrosion resistance of stainless steel. Large stainless steel factories with good smelting technology, advanced equipment and advanced technology can be guaranteed in the control of alloy elements, impurity removal and billet cooling temperature. Therefore, the product quality is stable and reliable, with good internal quality and not easy to rust. On the contrary, some small steel plants are backward in equipment and technology. During the smelting process, impurities cannot be removed and the products will inevitably rust.

  3. External environment, dry and ventilated environment is not easy to rust. And the air humidity, continuous rain weather, or the air contains acid and alkaline environment area is easy to rust. Like 304 material stainless steel, it will rust if the surrounding environment is too bad.
