Daxun Alloy's pure titanium Grade 1 titanium tubes include:
Our seamless and welded titanium tubes boast outstanding ductility and cold formability, perfect for deep drawing applications. Grade 1 titanium tubes are renowned for their superior general and seawater corrosion resistance and exceptional resilience against oxidizing, neutral, and slightly reducing media, including chlorides.
With low density (about half that of nickel-based alloys), titanium offers high strength, light weight, and corrosion resistance, making it an ideal choice for various harsh chemical environments. Compliance with standards: ASTM B338 | ASTM B265 | ASME SB265 | ASTM F67 | ISO 5832-2 | 3.7025 | UNS R50250.
Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
The most widely used titanium tube for industrial applications, it delivers an exceptional balance of moderate strength and reasonable ductility. Its excellent corrosion resistance in both highly oxidizing and slightly reducing conditions (including chlorides) makes it invaluable in chemical and offshore industries, aircraft manufacture, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping.
Fabrication
Grade 2 titanium excels in cold forming with standard methods and can be easily machined, provided sharp tools and liberal coolant are used. Similar to machining austenitic stainless steels, deep and continuous cuts with slow feeds and speeds are recommended.
Stock Availability
Daxun Alloys readily stocks CP 2 Grade Titanium Seamless and Welded Pipes in a wide range of sizes.
Weight Reduction
CP 2 grade titanium tubes, with their low density and high strength-to-weight ratio, are perfect for applications demanding weight reduction without compromising strength. Cold formable with good ductility, they can be welded using conventional TIG and MIG processes, though inert gas shielding is essential to prevent embrittlement in the weld zone.
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. Around 885°C [1625°F], it transforms into a beta (body-centered cubic) structure. This transformation temperature can be adjusted by the type and quantity of impurities or alloying additions. Alloying elements also create two temperature zones: the alpha transformation zone (below which the alloy is all alpha) and the beta transformation zone (above which the alloy is all beta). Between these temperatures, both alpha and beta forms 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 are meticulously crafted from hollow blanks through hot extrusion or oblique rolling and piercing, followed by multiple cold rolling processes. The production process ensures continuous perimeters throughout. Key steps in manufacturing include sponge titanium vacuum arc melting, ingot blanking for hollow blanks, cleaning, cutting and feeding, hot extrusion or oblique rolling + 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, employing the advanced automatic arc welding (TIG) process. Our streamlined production process encompasses several critical stages: uncoiling titanium plates, shearing, butt welding, thorough cleaning, precise pipe forming, TIG welding, rigorous eddy current testing, pre-sizing, annealing, precision reducing and sizing, straightening, another round of eddy current testing, caliper marking, cutting, ultrasonic testing, hydrostatic testing, culminating in a final inspection and meticulous packaging. Each welded pipe undergoes at least one essential stress relief heat treatment following forming and welding. At Daxun, we ensure the highest quality by using premium filler materials during the welding process.
Ti-6Al-4V Titanium Pipe - Grade 5 Titanium Tube
Titanium Alloy - (UNS R56400)
Introduction
Introducing DAXUN Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400), the epitome of titanium alloys in popularity and performance. This duplex alpha+beta titanium alloy masterfully incorporates aluminum as the alpha stabilizer and vanadium as the beta stabilizer. Renowned for its remarkable strength, this alloy thrives even at low temperatures as extreme as 800°F (427°C). Ideal for annealing, solution treating, and aging, the ATI Ti-6Al-4V, Grade 5 alloy is indispensable in manufacturing compressor blades, disks, and rings for jet engines; fuselage and space capsule components; pressure vessels; *** cases; helicopter rotor hubs; fasteners; and critical forgings, where a high strength-to-weight ratio is paramount.
The alloy's initial melting is expertly conducted using vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM) methods. Remelting may involve one or two meticulous vacuum arc steps, ensuring the highest quality and consistency.

The DAXUN Ti-6Al-4V Titanium Tube, Grade 5 is a tough customer at room temperature, even after annealing. For severe forming operations like bending or stretching, perform these at up to 1,200°F (649°C) to maintain its stellar mechanical properties. For hot sizing or forming, utilize creep forming within the 1,000 to 1,200°F (538 to 649°C) range for optimal performance.
Machinability
Machining the DAXUN Ti-6Al-4V Titanium Tube, Grade 5 is a task it handles with grace. Using methods designed for austenitic stainless steels, apply slow speeds, high feeds, and ensure robust tool rigidity. A generous application of non-chlorinated cutting fluids is recommended for a smooth machining process.
Weldability
The DAXUN Ti-6Al-4V Titanium Tube Grade 5 stands out with its exceptional weldability. Whether annealed or in a solution and partially aged condition, this tube is ready for seamless welding.
Post-weld heat treatment completes the process, with precautions to avoid contamination from gases like oxygen, nitrogen, and hydrogen. Fusion welding in an inert gas chamber or with an inert gas tail shield over the molten metal and surrounding hot zones ensures integrity. Spot welding, seam welding, and flash welding can be performed without protective atmospheres.
Special Considerations
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 requires special attention to avoid contamination from hydrogen during pickling, and from oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. Such contamination can compromise ductility and affect notch sensitivity and formability. Handle with care for the best performance.
