Weight Reduction
CP 2 grade titanium tubes are engineered for applications demanding significant weight reduction without compromising strength. Featuring a low density and high strength-to-weight ratio, they possess good ductility and are cold formable. These tubes can be welded using conventional TIG and MIG processes, with inert gas shielding essential to prevent weld zone embrittlement.
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. Around 885°C (1625°F), it transitions to a beta (body-centered cubic) structure. Impurities or alloying additions can alter this transformation temperature. Alloying elements further divide the equilibrium transformation temperature into alpha and beta zones, with alpha transformation below and beta transformation above. Typical alpha and beta transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F), respectively.
Grade 2 Titanium Seamless Pipe Manufacturing Process
Crafted to perfection, Daxun's ASTM B338 Grade 2 titanium seamless tubes are produced from hollow blanks through hot extrusion or oblique rolling and piercing. These processes are followed by multiple cold rolling operations. Throughout manufacturing, continuous perimeters are maintained. The comprehensive production of titanium seamless tubes involves: vacuum arc melting of sponge titanium to create ingots, blanking to obtain hollow blanks, cleaning, cutting, feeding, hot extrusion or oblique rolling and piercing, degreasing, drying, cutting, online annealing, 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 pipe is crafted from annealed flat-rolled steel plate or steel strip using an automatic arc welding (TIG) process. The comprehensive production processes include: titanium plate uncoiling, shearing, butt welding, cleaning, pipe forming, TIG welding, eddy current testing, pre-sizing, annealing, precision reducing and sizing, straightening, eddy current testing, caliper marking, cutting, ultrasonic testing, hydrostatic testing, final inspection, and packaging. Welded pipes undergo at least one stress relief heat treatment after forming and welding. Daxun ensures the use of appropriate filler materials during the welding process.
Ti-6Al-4V Titanium Pipe - Grade 5 Titanium TubeTitanium Alloy - (UNS R56400)
Introduction
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400) stands as the most sought-after titanium alloy. It's a duplex alpha+beta titanium alloy utilizing aluminum as the alpha stabilizer and vanadium as the beta stabilizer. This high-strength material is operable at temperatures dipping to about 800°F (427°C). The ATI Ti-6Al-4V, Grade 5 alloy is suitable for annealing, solution treating, and aging processes. Its applications span compressor blades, disks, and rings for jet engines; fuselage and space capsule components; pressure vessels; *** cases; helicopter rotor hubs; fasteners; and critical forgings requiring a high strength-to-weight ratio.
The alloy initially undergoes melting through vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM) techniques. Remelting is often conducted in one or two vacuum arc steps to ensure purity.

Forgeability/Formability DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube showcases exceptional forgeability when processed correctly. It is best forged at a high temperature of 1,750°F (954°C) and should conclude forging at 1,450°F (788°C). For optimal results, a minimum reduction of 35% is highly recommended.
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube presents challenges in forming at room temperature, even post-annealing. However, it excels in severe forming operations like bending or stretching at elevated temperatures up to 1,200°F (649°C) without losing its mechanical integrity. For hot sizing or forming, creep forming is an ideal method, applicable at temperatures between 1,000 and 1,200°F (538 to 649°C).
Machinability DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube is amenable to machining with techniques used for austenitic stainless steels. Employ slow speeds, high feeds, and ensure robust tool rigidity. Generous use of non-chlorinated cutting fluids is essential to achieve precision and maintain integrity.
Weldability The DAXUN Ti-6Al-4V Titanium Tube Grade 5 Titanium Tube is highly weldable in both the annealed and solution-aged conditions. Post-weld heat treatment allows for efficient aging.
During welding, it's critical to prevent contamination from oxygen, nitrogen, and hydrogen to maintain material integrity. Fusion welding is best performed in an inert gas-filled chamber or with an inert gas tail shield to protect the molten metal and adjacent hot zones. Spot welding, seam welding, and flash welding can be executed without protective atmospheres.
Special Considerations The DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube is susceptible to hydrogen contamination from improper pickling and absorption of oxygen, nitrogen, and carbon during forging, heat treating, and brazing. Such contamination can compromise ductility and negatively affect notch sensitivity and formability.
