Daxun Alloy's pure titanium Grade 1 tubes include:
Seamless and welded titanium tubes, celebrated for their remarkable ductility and cold formability, are perfect for deep drawing. Grade 1 titanium tubes offer outstanding general and seawater corrosion resistance, along with excellent resistance to oxidizing, neutral, and slightly reducing media (solutions), including chlorides.
Titanium's low density (roughly half that of nickel-based alloys), high strength, and light weight, combined with superior corrosion resistance, make it an ideal choice for demanding chemical environments. Our execution standards include ASTM B338, ASTM B265, ASME SB265, ASTM F67, ISO 5832-2, 3.7025, and UNS R50250.
Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
This titanium tube is the go-to choice for industrial applications, thanks to its exceptional balance of moderate strength and excellent ductility. It boasts superb corrosion resistance under highly oxidizing and slightly reducing conditions, including chlorides. This makes it indispensable in the chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping systems.
Fabrication
Titanium Grade 2 is highly amenable to cold forming using standard techniques. Machining it requires careful attention to tool sharpness and liberal use of coolant. Similar to working with austenitic stainless steels, deep and continuous cuts with slow feed rates and speeds are recommended.
Stock Availability
Daxun Alloys maintains an extensive inventory of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes.
Weight Reduction
CP 2 grade titanium tubes are prized for their low density and high strength-to-weight ratio, making them perfect for weight-sensitive applications. They are cold formable, possess excellent ductility, and can be welded using conventional TIG and MIG techniques, with inert gas shielding necessary to prevent weld zone embrittlement.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tube exhibits an alpha (hexagonal close-packed) crystal structure, similar to commercially pure titanium grades 1 and 3. The structure changes to beta (body-centered cubic) at approximately 885°C (1625°F). Alloying elements can modify these transformation temperatures, creating two distinct temperature zones: the alpha transformation zone, where the alloy is entirely alpha, and the beta transformation zone, where the alloy is entirely beta. Between these zones, both alpha and beta phases coexist. Typical transformation temperatures for Grade 2 titanium are 890°C (1635°F) for alpha and 913°C (1675°F) for beta.
Grade 2 Titanium Seamless Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium seamless tubes begin with hot extrusion or oblique rolling and piercing of hollow blanks, followed by multiple cold rolling stages. The seamless tubes maintain continuous perimeters throughout manufacturing. The production steps include: sponge titanium vacuum arc melting, ingot blanking to obtain hollow blanks, 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 pipe is meticulously crafted from annealed flat-rolled steel plate or steel strip using a state-of-the-art automatic arc welding (TIG) process. Our comprehensive production journey involves: uncoiling and shearing titanium plate, butt welding, thorough cleaning, pipe formation, TIG welding, rigorous eddy current testing, pre-sizing, precise annealing, precision reducing and sizing, straightening, a second eddy current testing, caliper marking, cutting, ultrasonic testing, hydrostatic testing, and a final meticulous inspection before packaging. Every welded pipe undergoes stress relief heat treatment post forming and welding to ensure superior quality. Daxun ensures no filler materials are used during the welding process, maintaining the highest standards of purity and performance.
Ti-6Al-4V Titanium Pipe - Grade 5 Titanium TubeTitanium Alloy - (UNS R56400)
Introduction
DAXUN Ti-6Al-4V Titanium Tube, also known as Grade 5 (UNS R56400), stands as the most sought-after titanium alloy. This duplex alpha+beta titanium alloy incorporates aluminum as the alpha stabilizer and vanadium as the beta stabilizer. Renowned for its exceptional strength, this alloy operates efficiently at low temperatures around 800°F (427°C). ATI Ti-6Al-4V, Grade 5 alloy is ideal for annealing, solution treating, and aging. Its applications span across compressor blades, disks, and rings for jet engines; fuselage and space capsule components; pressure vessels; *** cases; helicopter rotor hubs; fasteners; and critical forgings that demand a high strength-to-weight ratio.
The alloy is initially melted using advanced vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM) techniques. Subsequent remelting is performed in one or two vacuum arc steps to ensure purity and uniformity.

Optimum Properties Optimal properties are achieved with small cross sections and rapid quenching in the solution-treated and aged state. Larger cross-sections or delayed quenching might result in less than ideal properties.
HardnessTypical hardness ranges from Rockwell C 30-34 in the annealed condition to approximately Rockwell C 35-39 in the solution-treated and aged state.
Forgeability/Formability The high-performance DAXUN Ti-6Al-4V Titanium Tube, recognized as Grade 5 Titanium Tube, is meticulously forged at a precise temperature of 1,750°F (954°C), with a critical final forging temperature of 1,450°F (788°C). For optimal structural integrity and performance, a reduction of at least 35% is highly recommended.
Our DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, presents challenges in forming at room temperature, even post-annealing. However, intense forming operations, including bending and stretching, can be efficiently executed on annealed materials at elevated temperatures of up to 1,200°F (649°C) without altering its mechanical properties. For hot sizing or forming, creep forming processes are effective within the temperature range of 1,000 to 1,200°F (538 to 649°C).
Machinability The DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, is compatible with standard machining methods used for austenitic stainless steels. Optimal machining requires slow speeds, elevated feeds, robust tool rigidity, and ample use of non-chlorinated cutting fluids to achieve precision and quality.
Weldability The DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, offers exceptional weldability in both annealed and solution-treated as well as partially aged conditions, with aging.
successfully completed during post-weld heat treatment. It is crucial to prevent contamination by oxygen, nitrogen, and hydrogen during the process. Fusion welding should be conducted in an inert gas-filled chamber or with an inert gas tail shield protecting the molten metal and adjacent hot zones. Alternative welding methods such as spot welding, seam welding, and flash welding can be performed without a protective atmosphere.
Special Considerations While working with DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube, care must be taken to avoid hydrogen contamination from improper pickling processes and the absorption of oxygen, nitrogen, and carbon during forging, heat treating, or brazing. Such contamination can significantly reduce its ductility and negatively impact notch sensitivity and formability.
