The main factors affecting the corrosion of stainless steel plates
The surface of stainless steel plate is smooth and has strong plasticity. Generally, it is not easy to rust, but it is not absolute.
There are three main factors that affect the corrosion of stainless steel plates:
1.The content of alloying elements. Generally speaking, steel with a chromium content of 10.5% is less prone to rusting. The higher the content of chromium and nickel, the better the corrosion resistance. For example, 304 material requires a nickel content of 8-10% and a chromium content of 18-20%. Such stainless steel will not rust under normal circumstances.
2. The smelting process of production enterprise Jinzhe can also affect the corrosion resistance of stainless steel. Large stainless steel plants with good smelting technology, advanced equipment, and advanced processes can ensure the control of alloy elements, removal of impurities, and control of cooling temperature of steel billets. Therefore, the product quality is stable and reliable, with good internal quality and less prone to rusting. On the contrary, some small steel mills have outdated equipment and processes. During the smelting process, impurities cannot be removed, and the products produced will inevitably rust.
3. The external environment is dry and well ventilated, making it less prone to rusting. Areas with high air humidity, continuous rainy weather, or high acidity and alkalinity in the air are prone to rusting. Jinzhe 304 stainless steel plate can also rust if the surrounding environment is too poor.
In fact, chromium is a highly chemically stable element in stainless steel plates. It can form an extremely stable oxide film on the surface of the steel, isolating the metal from the air, thus protecting the steel plate from oxidation and increasing its corrosion resistance.
