321 Stainless Steel Pipes
We supply 321 stainless steel pipes, a titanium-stabilized austenitic stainless steel tubing designed to resist intergranular corrosion in welded and high-temperature applications. With added titanium forming stable carbides, this grade prevents carbide precipitation in the sensitization temperature range, making it ideal for piping systems exposed to elevated temperatures and corrosive media.

Product Description

不锈钢 拷贝


  • Intergranular Corrosion Resistance: Titanium stabilization effectively prevents carbide precipitation at 450–850°C, maintaining corrosion resistance in welded and heat-affected zones.

  • High-Temperature Performance: Suitable for continuous service up to 800°C, with good oxidation and scaling resistance in air and combustion atmospheres.

  • Excellent Formability and Weldability: Maintains the workability of austenitic stainless steel, supporting bending, flanging, and standard welding methods.

  • Versatile Corrosion Resistance: Performs well in acidic, alkaline, and chloride-containing environments, including organic acids and mild industrial media.

Applications
Ideal for heat exchanger tubes, furnace piping, boiler systems, aircraft exhaust manifolds, chemical processing equipment, and welded high-temperature structural components.

We provide pipes in various diameters, wall thicknesses, and lengths, with options for cutting, beveling, threading, polishing, and hydrostatic testing. Full material certification compliant with ASTM A312, EN 10216-5, JIS G3459, and related standards is included to ensure quality and traceability.
