The third-generation Hastelloy alloy alloy20 is one of the more commonly used components in the C series. Due to its low nickel content, low cost, excellent mechanical and corrosion resistance, it is widely used in pump flow components where corrosion and wear coexist. The solubility of hardness in the ferrite phase reaches its maximum at 850, and as the temperature increases, the solubility increases rapidly and is much smaller than that of the austenite phase. The Cu content in c-276 has exceeded the high solubility in the ferrite phase. The Hastelloy alloy alloy20, formed by a large amount of Ni element composition, is used in industries such as chemical engineering, pharmaceuticals, seawater, fertilizers, and other industries for projects with high corrosion resistance requirements due to its unique characteristics that lie between ferrite and austenite structures, and its resistance to intergranular corrosion. In recent years, the nuclear power industry has developed a corrosion-resistant ability in the operation of power station equipment, which cannot be replaced by other materials. Containing a large amount of Cr component, with high oxidation resistance. The molybdenum element in stainless steel materials is only about 2%, which is far less than the molybdenum content of Hastelloy alloy alloy20. Therefore, high concentration acidity requires the use of materials well. Mainly used, it has the following corrosion resistance properties in oxidation and reduction, and excellent corrosion resistance to most corrosive media. In this oxidizing environment, such as in sulfuric acid manufacturing and solutions containing a large amount of oxidizing ions, it has excellent resistance to pitting corrosion, crevice corrosion, and stress corrosion.
