Daxun Alloy's pure titanium Grade 1 titanium tubes include:
Seamless titanium tubes and welded titanium tubes, which boast outstanding ductility and cold formability, perfect for deep drawing applications. Grade 1 titanium tubes are renowned for their exemplary general and seawater corrosion resistance. They excel in resisting oxidizing, neutral, and slightly reducing media (solutions), including chlorides.
Titanium's low density (approximately half that of nickel-based alloys), combined with its high strength, lightweight nature, and superior corrosion resistance, make it the optimal choice for a wide array of harsh chemical environments. Available execution standards include: 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)
This is the most widely utilized titanium tube for industrial purposes, providing an exceptional balance of moderate strength and considerable ductility. It offers outstanding corrosion resistance under both highly oxidizing and slightly reducing conditions, including chlorides. This grade is extensively used in the chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire and ballast water systems, industrial and aerospace components, CPI equipment, and piping solutions.
Fabrication
Titanium Grade 2 performs excellently in cold forming using standard techniques. It is readily machinable, though it requires sharp tools and abundant coolant. Similar to machining austenitic stainless steels, cuts should be deep and continuous with slow feeds and speeds.
Stock Availability
Daxun Alloys maintains a diverse inventory of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes.
Weight Reduction
CP 2 grade titanium tubes are characterized by their low density and high strength-to-weight ratio, making them ideal for applications that demand weight reduction without compromising strength. These tubes are cold formable, exhibit good ductility, and can be welded using conventional TIG and MIG processes, though inert gas shielding is necessary to avoid embrittlement of the weld zone.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tube possesses an alpha (hexagonal close-packed) crystal structure, similar to commercially pure titanium grades 1 and 3. At approximately 885°C [1625°F], it transitions to a beta (body-centered cubic) structure. This transformation temperature can vary based on the impurities or alloying additions. The inclusion of alloying elements shifts the single equilibrium transformation temperature into two distinct zones: the alpha transformation zone, where the alloy remains all alpha, and the beta transformation zone, where the alloy is entirely 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.
Grade 2 Titanium Seamless Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium seamless tubes are meticulously crafted from hollow blanks through the hot extrusion process or oblique rolling and piercing process, followed by multiple cold rolling stages. Throughout manufacturing, titanium seamless tubes must maintain continuous perimeters. The comprehensive 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 manufactured using the automatic arc welding (TIG) process on annealed flat-rolled steel plates or steel strips. The comprehensive production process includes: 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. Our welded pipes undergo at least one stress relief heat treatment post-forming and welding. Daxun ensures no filler materials are used during the welding process, guaranteeing the highest quality and integrity.
Ti-6Al-4V Titanium Pipe - Grade 5 Titanium TubeTitanium Alloy - (UNS R56400)
Introduction
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400) is the premier titanium alloy renowned for its exceptional strength and versatility. This duplex alpha+beta titanium alloy incorporates aluminum as the alpha stabilizer and vanadium as the beta stabilizer, enabling use at low temperatures up to approximately 800°F (427°C). ATI Ti-6Al-4V, Grade 5 alloy is ideal for annealing, solution treating, and aging processes. It is widely utilized in manufacturing critical components such as compressor blades, disks, and rings for jet engines; fuselage and space capsule elements; pressure vessels; *** casings; helicopter rotor hubs; fasteners; and high strength-to-weight ratio forgings.
The alloy undergoes initial melting using advanced techniques such as vacuum arc remelting (VAR), electron beam (EB), or plasma arc hearth melting (PAM). Subsequent remelting is performed in one or two vacuum arc steps to ensure optimal purity and consistency.

Machinability DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube can be meticulously machined using techniques similar to those for austenitic stainless steels. Employ slow speeds, high feeds, robust tool rigidity, and abundant non-chlorinated cutting fluids to achieve precision and efficiency.
Weldability DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube demonstrates excellent weldability in both annealed and solution-aged conditions. Aging is effectively achieved during post-weld heat treatment. Take necessary precautions against contamination by oxygen, nitrogen, and hydrogen. Fusion welding can be performed in an inert gas-filled chamber or using an inert gas tail shield over the molten metal and adjacent hot zones. For added versatility, spot welding, seam welding, and flash welding can be performed without a protective atmosphere.
Specialized care during post-weld heat treatment is crucial to achieving optimal results. Avoid oxygen, nitrogen, and hydrogen contamination during the process. For fusion welding, an inert gas-filled chamber or an inert gas tail shield over the molten metal and hot zones is essential. Spot welding, seam welding, and flash welding can be conducted without a protective atmosphere for seamless results.
Special Considerations Ensure the purity and performance of the DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube by preventing hydrogen contamination from improper pickling and avoiding the absorption of oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. Such contamination can diminish ductility and negatively impact notch sensitivity and formability.
