Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
Our Grade 2 Titanium Tube is the industry's favorite for a myriad of industrial applications, striking the perfect balance between moderate strength and excellent ductility. Renowned for its outstanding corrosion resistance in both highly oxidizing and mildly reducing environments, including chlorides, this tube is indispensable in the chemical and offshore industries, as well as in aircraft manufacturing where both strength and formability are paramount. Additionally, it is widely used in heat exchangers, hypochlorite systems, fire water systems, ballast water systems, CPI equipment, industrial and aerospace components, and piping solutions.
Precision Fabrication
Titanium Grade 2's adaptability to cold forming using conventional methods is noteworthy. It is highly machinable, provided that tools remain sharp and coolants are generously applied. Similar to working with austenitic stainless steels, machining should involve deep, continuous cuts with slow feed rates and speeds to ensure precision and effectiveness.

Innovative Weight Reduction
Our CP 2 grade titanium tubes stand out due to their low density and high strength-to-weight ratio, making them ideal for applications where reducing weight is critical without compromising strength. These tubes are also highly formable, offer good ductility, and can be welded using standard TIG and MIG processes, with inert gas shielding necessary to avoid weld zone embrittlement.
Advanced Crystal Structure
At ambient temperatures, the Grade 2 titanium tube adheres to an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. As temperatures climb to approximately 885°C (1625°F), it transitions to a beta (body-centered cubic) structure. The transformation temperatures can be adjusted based on impurity levels or alloying additions, which also create two distinct temperature zones: the alpha transformation zone (all alpha) and the beta transformation zone (all beta). Between these zones, both alpha and beta phases coexist, with typical transformation temperatures for Grade 2 titanium being 890°C (1635°F) and 913°C (1675°F), respectively.

Weight Reduction
CP 2 grade titanium tubes boast low density and an exceptional strength-to-weight ratio, ideal for applications necessitating weight reduction without compromising strength. These tubes are cold formable, exhibit excellent ductility, and are compatible with conventional TIG and MIG welding processes, provided inert gas shielding is employed to prevent weld zone embrittlement.
Crystal Structure
At ambient temperature, ASTM B338 Grade 2 titanium exhibits an alpha (hexagonal close-packed) crystal structure, akin to 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 altered by varying the type and quantity of impurities or alloying elements. These additions bifurcate the equilibrium transformation temperature into two zones: the alpha transformation zone (entirely alpha below) and the beta transformation zone (entirely beta above). Between these zones, both alpha and beta phases coexist. Typical transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F).
Grade 2 Titanium Seamless Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium seamless tubes are meticulously crafted from hollow blanks through hot extrusion or oblique rolling and piercing.
