321 Seamless Stainless Finned Tubes
Composition and structure: 321 seamless stainless steel pipe is mainly composed of iron, chromium, nickel and other elements, and contains elements such as titanium and nitrogen for stabilization. Its metallographic structure is austenite and has a single-phase austenite structure. This organizational structure gives the steel pipe excellent corrosion resistance and high temperature performance.
Corrosion resistance: Due to the titanium content, 321 seamless stainless steel pipe has excellent corrosion resistance in complex environments such as oxidizing, reducing and neutral salts. It has excellent resistance to pitting corrosion, crevice corrosion and stress corrosion, and can resist corrosion by various acids, alkalis, salts and other chemical substances.
High temperature performance: 321 seamless stainless steel pipe can still maintain good mechanical properties and corrosion resistance at high temperatures. It has a wide operating temperature range and can be used for a long time in the temperature range of -29°C to 425°C, and can withstand short-term high temperatures to about 500°C.
Mechanical properties: 321 seamless stainless steel pipe has excellent mechanical properties, such as high strength, high toughness, low expansion coefficient, etc. Its tensile strength, yield point, elongation and other indicators all meet the requirements of the ASTM A312 standard.
Application fields: Due to its excellent corrosion resistance and high temperature performance, 321 seamless stainless steel pipe is widely used in petroleum, chemical industry, pharmaceutical, food processing, thermal pipe network and other fields. It can be used as pipes for high-temperature and high-pressure pipelines, thermal equipment, reactors and other equipment, and can meet the use requirements in various complex environments.
