SUS 321 stainless steel seamless pipe

321 stainless steel is an austenitic stainless steel grade that is stabilized with titanium. The addition of titanium helps to prevent sensitization and intergranular corrosion that can occur in certain environments, particularly during welding or exposure to high temperatures. The composition of 321 stainless steel typically includes about 17-19% chromium, 9-12% nickel, 0.08% carbon, 2% maximum manganese, 0.75% maximum silicon, 0.03% maximum sulfur, 0.10% maximum nitrogen, and the titanium stabilizing element.

321 stainless steel seamless pipe introduction：

The stabilization provided by titanium in 321 stainless steel makes it suitable for applications where exposure to high temperatures is expected. It offers excellent resistance to oxidation and can withstand temperatures up to approximately 870°C (1600°F) in intermittent service and 925°C (1700°F) in continuous service. This makes 321 stainless steel pipes suitable for applications in industries such as aerospace, power generation, chemical processing, and exhaust systems.

In addition to its high-temperature capabilities, 321 stainless steel also exhibits good mechanical properties, including high tensile strength and excellent formability. It is also resistant to corrosion in various environments, including organic acids and many inorganic chemicals. However, it may not be as corrosion resistant as some other stainless steel grades, such as 316, in certain aggressive environments.

321 stainless steel pipes are available in a range of sizes and schedules to suit different applications. They are used for conveying fluids and gases, particularly in high-temperature and corrosive environments. When selecting a stainless steel pipe, it's important to consider factors such as temperature, pressure, chemical compatibility, and specific project requirements to ensure the appropriate material is chosen.
