Here is a detailed introduction to the performance of 321 stainless steel pipe:
1,Corrosion Resistance: The addition of titanium as a stabilizing element gives 321 stainless steel pipe excellent resistance to intergranular corrosion, which is a common problem in stainless steel materials that have been exposed to high temperatures. It also provides good resistance to pitting and crevice corrosion, making it suitable for use in harsh environments such as chemical processing plants, oil refineries, and marine applications.
2,High-Temperature Resistance: 321 stainless steel pipe can withstand high temperatures ranging from 800-1500°F (427-816°C). This makes it an ideal material for applications that involve exposure to high heat, such as furnace components, heat exchangers, and exhaust systems.
3,Mechanical Properties: 321 stainless steel pipe has good mechanical properties, including high strength, toughness, and ductility. It also has a low coefficient of thermal expansion, which makes it resistant to thermal stress cracking.
4,Weldability: 321 stainless steel pipe is easy to weld and can be welded using most conventional welding methods. However, care must be taken to avoid weld cracking, and the material must be properly annealed after welding to maintain its corrosion resistance.
5,Formability: 321 stainless steel pipe can be formed into various shapes and sizes using conventional methods such as bending, rolling, and stamping. However, due to its high strength, it may require more force to form than other stainless steel materials.
