Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
This grade is the industry's preferred titanium tube for its exceptional balance of moderate strength and ductility. It excels in highly oxidizing and slightly reducing conditions, including chlorides, making it indispensable in chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, and CPI equipment. Its versatility extends to a myriad of industrial and aerospace components.
Fabrication
Titanium Grade 2 is highly responsive to cold forming using standard methods. It can be efficiently machined, but meticulous care is required to maintain sharp tools and ample coolant application. Similar to machining austenitic stainless steels, deep and continuous cuts with slow feeds and speeds are recommended.
Stock Availability
Daxun Alloys proudly maintains a diverse inventory of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes to meet your specific needs.
Weight Reduction
The CP 2 grade titanium tubes boast low density and a high strength-to-weight ratio, perfect for applications necessitating weight reduction without compromising strength. These tubes are cold formable, ductile, and can be welded using conventional TIG and MIG methods, with inert gas shielding to prevent weld zone embrittlement.
Crystal Structure
At ambient temperature, ASTM B338 Grade 2 titanium tubes exhibit an alpha (hexagonal close-packed) crystal structure, identical to grades 1 and 3 of commercially pure titanium. At approximately 885°C (1625°F), they transform into a beta (body-centered cubic) structure. The transformation temperature can vary based on impurity or alloying elements. Alloying additions also bifurcate the equilibrium transformation temperature into alpha and beta zones, with typical transformation temperatures for grade 2 titanium being 890°C (1635°F) and 913°C (1675°F), respectively.
Grade 2 Titanium Seamless Pipe Manufacturing Process
Our premium ASTM B338 Grade 2 titanium seamless tubes are crafted using hollow blanks through hot extrusion or oblique rolling and piercing, followed by multiple cold rolling processes. The comprehensive manufacturing process includes: vacuum arc melting of sponge titanium, blanking, 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 meticulously crafted from annealed flat-rolled steel plate or steel strip using the sophisticated automatic arc welding (TIG) process. The comprehensive production process includes: 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. Notably, these welded pipes undergo at least one stress relief heat treatment post forming and welding to ensure optimal performance. Daxun ensures precision with the use of any filler materials during the welding process.
Ti-6Al-4V Titanium Pipe - Grade 5 Titanium Tube
Titanium Alloy - (UNS R56400)
Introduction
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400), stands as the pinnacle among titanium alloys. This sophisticated duplex alpha+beta titanium alloy leverages aluminum as the alpha stabilizer and vanadium as the beta stabilizer. Renowned for its high-strength, it remains effective at low temperatures of approximately 800°F (427°C). The ATI Ti-6Al-4V, Grade 5 alloy is meticulously utilized for annealing, solution treating, and aging. Its applications span a wide array of critical components such as compressor blades, disks, and rings for jet engines; fuselage and space capsule parts; pressure vessels; *** casings; helicopter rotor hubs; fasteners; and high strength-to-weight ratio forgings.
The alloy's initial melting is accomplished using advanced techniques such as vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM). Subsequent remelting is performed in one or two vacuum arc stages to ensure purity and consistency.

Optimum Properties
Optimal properties are achieved in small cross-sections with rapid quenching in the solution treated and aged condition. Conversely, larger cross-sections and/or delayed quenching may result in sub-optimal properties.
Hardness
Typical hardness in the annealed condition ranges from Rockwell C 30-34 and approximately Rockwell C 35-39 in the solution treated and aged condition.
Forgeability/Formability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube is meticulously forged at a precise temperature of 1,750°F (954°C) with a final forging touchpoint at 1,450°F (788°C). For exceptional results, a reduction of no less than 35% is recommended.
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube presents challenges in forming at room temperatures, even when annealed. Therefore, rigorous forming operations such as bending or stretching are best performed on annealed material at elevated temperatures up to 1,200°F (649°C) without altering its mechanical properties. Hot sizing or forming through creep forming can be conducted at temperatures between 1,000 and 1,200°F (538 to 649°C).
Machinability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube can be precision-machined using methods tailored for austenitic stainless steels. This includes slow speeds, high feeds, robust tool rigidity, and the abundant use of non-chlorinated cutting fluids.
Weldability
DAXUN Ti-6Al-4V Titanium Tube Grade 5 Titanium Tube is effortlessly weldable in both annealed or solution-treated, partially aged conditions. Post-weld heat treatment is used for aging.
Post-weld heat treatment ensures aging. To prevent contamination, safeguards against oxygen, nitrogen, and hydrogen must be employed. Fusion welding can be effectively performed in an inert gas-filled chamber or using an inert gas tail shield over the molten metal and adjacent hot zones. Techniques like spot welding, seam welding, and flash welding can be performed without a protective atmosphere.
Special Considerations
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube may risk contamination from hydrogen during improper pickling and from the absorption of oxygen, nitrogen, and carbon during forging, heat treating, and brazing. Such contamination could compromise ductility and weaken notch sensitivity and formability.
