Weight Reduction
The CP 2 grade titanium tubes stand out for their low density and superior strength-to-weight ratio, making them ideal for applications demanding weight reduction without compromising strength. These tubes boast excellent cold formability, superior ductility, and compatibility with conventional TIG and MIG welding processes, provided inert gas shielding is used to prevent weld zone embrittlement.
Crystal Structure
At room temperature, the ASTM B338 Grade 2 titanium tube features an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. Upon heating to approximately 885°C (1625°F), it transitions to a beta (body-centered cubic) structure. This transformation temperature can vary based on impurities or alloying elements. Alloying additions split the equilibrium transformation temperature into two distinct zones: the alpha transformation zone and the beta transformation zone. Between these zones, both alpha and beta forms coexist. Typical transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F) for the alpha and beta phases, respectively.
Grade 2 Titanium Seamless Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium seamless tubes are meticulously crafted from hollow blanks via hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. These seamless tubes feature continuous perimeters throughout the manufacturing process. Key steps include: sponge titanium vacuum arc melting, ingot blanking, hollow blank cleaning, cutting and feeding, hot extrusion or oblique rolling and piercing, degreasing, drying, cutting, online annealing and straightening, pickling, multiple cold rolling, degreasing, drying, vacuum annealing, straightening, cutting, pickling, final inspection, marking (DAXUN), and packaging.
Grade 2 Titanium Welded Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium welded pipes are produced from annealed flat-rolled steel plates or strips using the automatic arc welding (TIG) process.

Weight Reduction
With a low density and high strength-to-weight ratio, CP 2 grade titanium tubes are ideal for applications demanding weight reduction without compromising strength. They are easily cold formable, exhibit excellent ductility, and can be welded using standard TIG and MIG processes, although inert gas shielding is necessary to avoid embrittlement in the weld zone.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tube exhibits an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. At approximately 885°C (1625°F), it transforms into a beta (body-centered cubic) structure. This transformation temperature varies with the type and quantity of impurities or alloying additions. Alloying elements can adjust the single equilibrium transformation temperature into two distinct zones: the alpha transformation zone, below which the alloy remains all alpha, and the beta transformation zone, above which the alloy is all beta. Between these zones, both alpha and beta forms coexist. Typical alpha and beta transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F), respectively.
