Oem Aisi 321 Stainless Steel Round Tube Square Tube Seamless Tube

321 stainless steel is a popular and versatile austenitic stainless steel alloy. It is a stabilized version of the basic 18-8 stainless steel (304), with the addition of titanium (Ti) as a stabilizing element. The "321" in its name indicates the composition of the alloy, which typically consists of about 17-19% chromium, 9-12% nickel, and 0.5-1.0% titanium.

Here are some key features and properties of 321 stainless steel tubes:

1,Corrosion Resistance: 321 stainless steel offers excellent resistance to corrosion, particularly in high-temperature environments. It exhibits superior resistance to intergranular corrosion, making it suitable for applications where exposure to corrosive substances is a concern.

2,High Temperature Resistance: 321 stainless steel tubes can withstand high temperatures without significant scaling or loss of mechanical properties. They are designed to maintain their strength and corrosion resistance even at temperatures up to 900°C (1650°F), making them suitable for applications in heat exchangers, exhaust systems, and other high-temperature environments.

3,Stabilized against Chromium Carbide Formation: The addition of titanium in 321 stainless steel helps prevent the formation of chromium carbides during welding or exposure to elevated temperatures. This stabilization improves the resistance to intergranular corrosion and sensitization that can occur in other stainless steel grades.

4,Strength and Durability: 321 stainless steel tubes exhibit good strength, toughness, and durability. They can withstand mechanical and thermal stresses, making them suitable for applications that require reliable and long-lasting piping systems.

5,Weldability: 321 stainless steel tubes have excellent weldability. They can be easily welded using common techniques such as TIG (Tungsten Inert Gas) welding, MIG (Metal Inert Gas) welding, and shielded metal arc welding. This allows for easy fabrication and installation of the tubes in various configurations.
