As a commonly used stainless steel material, 14477 plays an important role in the industrial sector and in everyday life.
1.4477 is an austenitic stainless steel known for its excellent corrosion resistance. Its chemical composition includes: carbon (c) content less than 0030, the content of silicon (Si) is less than 100, the content of manganese (Mn) is less than 200, the content of phosphorus (p) is less than 0045, the content of sulfur (s) is less than 0030, the content of chromium (CR) is 280-30.0, the content of nickel (Ni) is 65-7.5％。In addition, it contains a certain amount of molybdenum (Mo) and nitrogen (N), of which the content of molybdenum is 20-2.5. The nitrogen content is 015-0.25％。The rational ratio of these elements gives 14477 has excellent corrosion resistance.
1.The corrosion resistance of 4477 is mainly reflected in the following aspects:
1.Resistance to intergranular corrosion: Intergranular corrosion is one of the common forms of corrosion in stainless steel, which can lead to a decrease in the mechanical properties of metal materials. And 14477 has excellent resistance to intergranular corrosion and is able to resist intergranular corrosion caused by welding or high-temperature treatment.
2.Antioxidant Properties:14477 can also maintain good oxidation resistance in high temperature environment, and is not easy to oxidize and embrittlement, so that its service life under high temperature conditions is greatly extended.
3.Corrosion resistance: 14477 is able to maintain the stability of its material itself in a variety of corrosive media, and has a wide range of applications. It has good resistance to some common corrosive media such as nitric acid, sulfuric acid, hydrochloric acid and chloride.
In addition to the above corrosion resistance, 14477 also has good strength and toughness, making it suitable for various machining and machining processes. It can be processed and formed by cold working, hot working, forging, welding, etc., which can meet the needs of different fields and industries.
In summary, 14477 has received extensive attention and application for its excellent corrosion resistance and good mechanical properties. In industrial production and daily life, we can see its wide application in chemical, petroleum, pharmaceutical, food processing and other fields. I believe that with the continuous progress of science and technology, 1The 4477 will have more application scenarios in the future.
