321 Stainless Steel Tube
321 Stainless Steel Tube is used in many industries. It is specially used for strength and in high temperatures. If we talk about its use, it can mainly be used in aerospace, the automobile industry, and chemical processing.
Main Features
- Since titanium cannot allow chromium carbide to form, it prevents it from oxidation as well as corrosion resistance of the alloy.
- Good for high-temperature applications, that is, exhaust systems, heat exchangers, and even power plants where most other materials cannot resist.
- Excellent Welding Properties: very weldable but may be ideal for fabrication and maintenance operations if fabricated and maintained properly; it doesn’t even show when welded.
- This Stainless Steel Tube is used in the aerospace, automotive as well as heavy engineering industries.
- Long-term construction: It is very stress-resistant and stands well even under extremely hostile conditions.

Advantages:
- It is doped with titanium. It prevents carbide precipitation in which tubes have to bear less stress from certain forces.
- It withstands corrosion and oxidation while working steadily without failures even at extreme temperatures and sour environments.
- When we talk about weldability, it has excellent properties. 321 stainless steel tube can easily find integration into processes, and offer ways to minimize downtime while maximizing productivity.
- It is best if we use it in boilers, various reactors, and other heat exchangers because those places need heat-resistant and corrosion-resistant material. In high-temperature applications, the 321 stainless steel tube is used in exhaust systems, etc.
Dimensions & Specification
- They come in different sizes to fit any project.
- You can place orders in any customized length and diameter.
- Specification per ASTM A312 and ASTM A213.

Stainless steel pipes are strong, durable and have a high resistance to corrosion. This makes them the obvious choice for applications in which water and/or gases need to be transported. Their strength offers good resistance against internal and external pressure, and they are ideal for use in situations where longitudinal stresses or complicated bending are likely. They also offer good resistance to vibration and shock.
