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.

Hollow Section steel Tube is the general name for the steel pipe other than thecircular steel pipe. Such as square, rectangle, oval,elliptical, cone, trapezoidal, spiral, etc. Different steel pipe can more adapt to the particularity of use conditions, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, light textile and boiler manufacturing. The methods of producing different pipes are cold pulling, electric welding, extrusion and hot rolling, etc. Compared with the round tube, the different tubes generally have a larger moment of inertia and cross section modulus, and have a large bending resistance and torsion resistance, which can greatly reduce the structural weight and save steel.
Stainless steel tube is a hollow long strip steel made of stainless-steel material. Because of its excellent corrosion resistance, it is mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipelines and mechanical structural components. In addition, when the bending and torsion strength are the same, the weight is light, so it is also widely used in manufacturing mechanical parts and engineering structures, but also commonly used in the field of furniture decoration. Stainless steel pipe is divided into seamless pipe and welding pipe according to the production mode, seamless steel pipe can be divided into hot rolling pipe, cold rolling pipe, cold pulling pipe and extrusion pipe, etc., cold pulling and cold rolling is the secondary processing of steel pipe; welding pipe is divided into straight welding pipe and spiral welding pipe. Stainless steel pipes can be divided into round tubes and different tubes according to the cross-sectional shape. The form tubes have rectangular tubes, rhomboid tubes, ellipse tubes, hexagonal tubes, octagonal tubes and various cross-sectional asymmetric tubes. It can be divided into Austenitic Stainless Steel Tube Ferritic Stainless Steel Tube Martensitic Stainless Steel Tube and Duplex Stainless Steel Tube by the type of stainless steel.
