Applications of 321 Stainless Steel Tubes
This special kind of stainless steel can be used in various industries thanks to the unique features it possesses. A few purposes for which it is ideal are given below:
Chemical Processing
321 stainless steel is a great choice for many applications in the chemical industry due to its features mentioned above. Its superior corrosion resistance makes it ideal for use in harsh environments, such as in petrochemical plants and wastewater treatment plants. Additionally, its high strength makes it suitable for structural components, storage tanks, and other equipment exposed to high temperatures. The formability and weldability features of 321 stainless steel allow for easy fabrication and assembly, making it a great choice for chemical processing and other applications.
Exhaust Manifold Manufacturing
Because of their heat and corrosion-resistant nature, 321 stainless steel tubes are often used for exhaust manifold manufacturing. The alloy is able to withstand extreme temperatures, making it ideal for use in high-performance engines. There is no worry of overheating and potential melting of the exhaust pipe. Additionally, its excellent formability and weldability allow for easy fabrication and assembly, making it a great choice for complex designs. The alloy’s superior corrosion resistance also means that it can withstand exposure to harsh environments, making it suitable for use in many vehicle exhaust applications.
Aircraft Collector Ring Manufacturing
Aircraft collector rings are components of an aircraft’s exhaust system that are designed to collect the exhaust from each engine and direct it away from the airframe. They are typically made from aluminum or stainless steel and are designed to reduce noise, vibrations, and emissions. Due to these same super mechanical properties, 321 stainless steel tubes are a great choice for aircraft collector rings. The alloy offers excellent strength and toughness, making it suitable for components exposed to high stresses and impacts.
