What kind of Stainless steel wire screen is not easy to rust? How to deal with rust?
There are three main factors that affect Stainless steel wire screen rust:
1. The content of alloying elements.
Generally speaking, the content of chromium is not easy to rust in 10.5% steel. The higher the chromium-nickel content, the better the corrosion resistance is. For example, the 304 material nickel content is 8-10%, and the chromium content is 18-20%. Such stainless steel will not rust under normal circumstances.
2. The smelting process of the production company also affects the corrosion resistance of The smelting process of the production company also affects the corrosion resistance of stainless steel.
The large stainless steel wire mesh plant with good smelting technology, advanced equipment and advanced technology can ensure the control of the alloy elements, the removal of impurities, and the control of the cooling temperature of the billet. Therefore, the product quality is stable and reliable, the internal quality is good, and it is not easy to rust. Conversely, some small steel wire mesh plants are behind and the process is behind. During the smelting process, impurities cannot be removed and the products will inevitably rust.External environment, dry and ventilated climate is not easy to rust.
3. External environment, dry and ventilated climate is not easy to rust.
Humidity in the air, continuous rainy weather, or air in areas with high pH, it is easy to rust. 304 stainless steel, if the surrounding environment is too bad it will rust.
How to deal with rust in stainless steel?
1. chemical method
The use of a pickling paste or spray to assist the re-passivation of the corroded part to form a chromium oxide film restores its resistance to corrosion. After pickling, it is important to flush properly with water in order to remove all contaminants and acid residues. After everything is processed, it is polished again with a polishing device and closed with a polishing wax. For those with slight rust on the spot, a 1:1 mixture of petrol and oil can be used to wipe off rust with a clean rag.
2. mechanical method
Blast cleaning, shot blasting with glass or ceramic particles, annihilation, brushing and polishing. Using mechanical methods it is possible to wipe off the contamination caused by previously removed materials, polishing materials or annihilation materials. All kinds of pollution, especially foreign iron particles, can be a source of corrosion, especially in humid environments. Therefore, the mechanical cleaning surface should preferably be cleaned in a dry condition. The mechanical method can only clean the surface and cannot change the corrosion resistance of the material itself. It is therefore recommended to re-polish with a polishing machine after mechanical cleaning and close it with a polishing wax.
