It seems that Christmas time is here once again, and it is time again to bring in the New Year. We wish the merriest of Christmas to you and your loved ones, and we wish you happiness and prosperity in the year ahead.Huzhou Nanxun Yintuo Special Material Technology Co., Ltd. specializes in the development and production of high-quality stainless steel seamless pipe and nickel-nickel alloys.
Stainless steel relies on a very thin, strong, dense and stable chromium-rich oxide film (protective film) formed on its surface to prevent oxygen atoms from continuing to penetrate and continue to oxidize, thereby obtaining the ability to resist corrosion. Once this film is continuously destroyed for some reason, oxygen atoms in the air or liquid will continuously infiltrate or iron atoms in the metal will continue to separate out, forming loose iron oxide, and the metal surface will continue to be rusted. There are many forms of damage to this surface film, and the following are more common in daily life:
1. The surface of stainless steel has accumulated dust containing other metal elements or attachments of heterogeneous metal particles. In humid air, the condensed water between the attachments and stainless steel connects the two into a micro battery, triggering an electrochemical reaction , The protective film is damaged, which is called electrochemical corrosion.
2. The surface of stainless steel adheres to the organic juice (such as melon, vegetable, noodle soup, sputum, etc.), which forms organic acid in the presence of water and oxygen, and the organic acid will corrode the metal surface for a long time.
3. The surface of stainless steel adheres to containing acid, alkali, and salt substances (such as alkaline water and lime water splashing on the decoration wall), causing local corrosion.
4. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, and nitrogen oxide), it will form sulfuric acid, nitric acid, and acetic acid liquid spots when encountering condensed water, causing chemical corrosion.
We are constantly moving forward, but we also see the stars and ambitious ambitions. For more information, please contact us: stainless steel pipe manufacturers. May the glow of Christmas candle fill your heart with peace and pleasure and make your New Year bright. Have a love filled Christmas and New Year!
