The reason for the rust of the 304 stainless steel pipe is that the surface of the stainless steel has a chromium-rich oxide film (protective film) to prevent the penetration and oxidation of oxygen atoms, thereby obtaining corrosion resistance. Once for some reason, this film is continuously destroyed, the oxygen atoms in the air or liquid will continue to penetrate or the iron atoms in the metal will continue to separate out, forming loose iron oxide, and the metal surface will continue to rust. The alloy without solution treatment will not dissolve into the matrix, resulting in a low content of matrix alloy.
Stainless steel plate is a kind of corrosion products is not easy, unless it's some serious condition actually not impossible to achieve in any products from corrosion, if our stainless steel plate from corrosion are likely to affect the normal use of it, so in order to avoid this situation and we need to do some preventive measures, the following we first to get to know what are the factors from corrosion of stainless steel plate?
Many daily necessities and facilities made of 3004 stainless steel are used in our daily life, such as 304 stainless steel water tanks, stainless steel sinks, etc. These 304 stainless steel products greatly facilitate people's lives, but people will also encounter To some merchants who use fake and true sub-charges to mislead consumers with fake 304 stainless steel plates or non-304 stainless steel plates, and bring immeasurable losses to consumers. Today, let ’s talk about how to identify the 304 stainless steel plate.true and false.
At present, with the continuous development of the industry, the requirements for various raw materials are getting higher and higher. Many new materials appear in our vision, such as 904L stainless steel plate, which is a new type of stainless steel material. Alloy 904L (UNS N08904) is a super austenitic stainless steel designed for medium to high corrosion resistance in a wide range of process environments. The combination of high chromium and high nickel content, plus the addition of molybdenum and copper, ensures good corrosion resistance.
