What Kind Of Stainless Steel Is Not Easy To Rust?
There are three main factors affecting the corrosion of stainless steel:
1. The content of alloying elements.
In general, steel with a chromium content of 10.5% is less likely to rust. The higher the content of chrome nickel, the better the corrosion resistance.
For example, the content of nickel in 304 material is 8-10%, and the content of chromium needs to be 18-20%. Such stainless steel will not rust under normal conditions.
2. The smelting process of the production enterprise will also affect the corrosion resistance of stainless steel.
The large stainless steel plant with good smelting technology, advanced equipment and advanced technology can guarantee the control of alloy elements, the removal of impurities and the control of the cooling temperature of the billet. Therefore, the quality of the product is stable and reliable, and the internal quality is good. On the contrary, some small steel mills are very backward and the process is backward. In the process of smelting, impurities cannot be removed, and the products produced will inevitably be rusted.
3. The external environment, the climate is dry and ventilated, the environment is less likely to rust.
The air humidity is high, such as continuous rainy weather, or the environment with large pH in the air is also very easy to rust.
Especially 304 stainless steel, if the surrounding environment is too bad, it will rust.
