Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
Grade 2 Titanium Tube is the industry-standard material for countless applications. Renowned for its perfect blend of moderate strength and impressive ductility, this tube excels in offering exceptional corrosion resistance under both highly oxidizing and slightly reducing environments, including exposure to chlorides. Its robust corrosion protection makes it indispensable in chemical and offshore industries and aircraft manufacturing, where strength and easy formability are paramount. It shines in heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping solutions.
Fabrication
Titanium Grade 2 is highly responsive to standard cold forming techniques. It can be easily machined, provided that tool sharpness is maintained and coolant is used liberally. Similar to machining austenitic stainless steels, it requires deep, continuous cuts with slow feeds and speeds for optimal results.

Weight Reduction
CP 2 Grade Titanium Tubes are designed to deliver an outstanding strength-to-weight ratio, ideal for applications demanding weight reduction without compromising strength. These tubes are cold formable, exhibit good ductility, and are easily weldable using conventional TIG and MIG processes, although inert gas shielding is imperative to prevent weld zone embrittlement.
Crystal Structure
At ambient temperatures, ASTM B338 Grade 2 Titanium Tube features an alpha (hexagonal close-packed) crystal structure, mirroring the properties of commercially pure Titanium Grades 1 and 3. Upon reaching approximately 885°C [1625°F], it transitions to a beta (body-centered cubic) structure. This transformation temperature can be adjusted with specific impurities or alloying additions. Alloying elements alter the single temperature of equilibrium transformation into two zones: the alpha transformation zone (below which the alloy is all alpha) and the beta transformation zone (above which the alloy is all beta). In the intermediate temperatures, both alpha and beta forms coexist. Typical transformation temperatures for Grade 2 Titanium are 890°C (1635°F) for alpha and 913°C (1675°F) for beta.

Weight Reduction
CP 2 grade titanium tubes are distinguished by their low density and superior strength-to-weight ratio, making them an excellent choice for applications demanding weight reduction without compromising overall strength. These tubes are cold formable, exhibit good ductility, and can be welded using conventional TIG and MIG processes, with careful inert gas shielding to prevent embrittlement in the weld zone.
Crystal Structure
The ASTM B338 Grade 2 titanium tube presents an alpha (hexagonal close-packed) crystal structure at room temperature, akin to commercially pure titanium grades 1 and 3. Upon reaching approximately 885°C (1625°F), it transforms into a beta (body-centered cubic) structure. This transformation temperature may vary with different impurities or alloying additions. The inclusion of alloying elements diversifies the equilibrium transformation into two temperature zones: the alpha transformation zone (all alpha alloy) and the beta transformation zone (all beta alloy). Between these temperatures, both alpha and beta forms coexist, with typical transformation temperatures for Grade 2 titanium being 890°C (1635°F) and 913°C (1675°F), respectively.

Machinability Experience the precision of the DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube. Our product can be machined with the same techniques used for austenitic stainless steels. By employing slow speeds, high feeds, and ensuring robust tool rigidity, coupled with abundant use of non-chlorinated cutting fluids, optimal machining performance is achieved.
Weldability The DAXUN Ti-6Al-4V Titanium Tube Grade 5 Titanium Tube exhibits exceptional weldability. Whether in the annealed state or the solution and partially aged conditions, our titanium tube is easily weldable. Ensure proper aging during post-weld heat treatment for best results.
Take steps to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding is best performed in an inert gas-filled chamber or with an inert gas tail shield covering the molten metal and adjacent hot areas. Additionally, spot welding, seam welding, and flash welding can be executed without a protective atmosphere.
Special Considerations When working with the DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, be cautious of contamination risks. Hydrogen may be introduced through improper pickling, and oxygen, nitrogen, and carbon absorption during forging, heat treating, brazing, etc., which can diminish ductility and affect notch sensitivity and formability. Handle with care to maintain the tube's superior properties.
