Daxun Alloy's Pure Titanium Grade 1 Tubes Include:
Our seamless and welded titanium tubes boast exceptional ductility and cold formability, making them perfect for deep drawing applications. Grade 1 titanium tubes stand out for their superior general and seawater corrosion resistance, as well as their remarkable resistance to oxidizing, neutral, and slightly reducing environments, including chloride solutions.
With a low density (approximately half that of nickel-based alloys), high strength, lightweight, and excellent corrosion resistance, titanium is an outstanding choice for various harsh chemical conditions. Compliance 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)
Grade 2 titanium tubes are the go-to choice for industrial applications, offering an exceptional balance of moderate strength and good ductility. They provide excellent corrosion resistance in highly oxidizing and slightly reducing environments, including chloride-rich settings. Ideal for the chemical and offshore industries, as well as aircraft manufacturing where strength and formability are paramount. These tubes are also used in heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and pipes.
Fabrication
Titanium Grade 2 adapts well to cold forming using standard methods. It can be easily machined, but special care must be taken to maintain sharp tools and use plenty of coolant. Similar to machining austenitic stainless steels, the cuts should be deep and continuous, with slow feeds and speeds.
Stock Availability
Daxun Alloys maintains a vast stock of CP 2 Grade Titanium Seamless and Welded Pipes in a variety of sizes.
Weight Reduction
CP 2 grade titanium tubes, known for their low density and high strength-to-weight ratio, are perfect for applications requiring weight reduction without compromising strength. These tubes are cold formable, possess good ductility, and can be welded using conventional TIG and MIG processes, though inert gas shielding is necessary to prevent embrittlement of the weld zone.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tubes exhibit an alpha (hexagonal close-packed) crystal structure, similar to commercially pure titanium grades 1 and 3. Around 885°C (1625°F), they transform into a beta (body-centered cubic) structure. This transformation temperature can vary based on the type and quantity of impurities or alloying additions. Alloying elements also divide the single equilibrium transformation temperature into two distinct 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 zones, 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
Crafted with precision, Daxun's ASTM B338 Grade 2 titanium seamless tubes are made from hollow blanks using hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. The manufacturing process involves the following steps: sponge titanium vacuum arc melting, ingot blanking to obtain hollow blanks, cleaning, cutting, 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 crafted from annealed flat-rolled steel plates or steel strips utilizing the advanced automatic arc welding (TIG) process. 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, caliper marking, cutting, ultrasonic testing, hydrostatic testing, final inspection, and packaging. Each welded pipe undergoes mandatory stress relief heat treatment post-forming and welding to ensure quality. Daxun employs any filler materials during the welding to enhance the joint integrity.
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 pre-eminent titanium alloy, renowned for its duplex alpha+beta composition, leveraging aluminum as the alpha stabilizer and vanadium as the beta stabilizer. This robust alloy performs exceptionally at low temperatures around 800°F (427°C). ATI Ti-6Al-4V, Grade 5, undergoes processes such as annealing, solution treating, and aging. Its applications span from compressor blades, disks, and rings for jet engines to 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 begins its journey through initial melting using vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM). This is followed by one or two vacuum arc remelting steps to refine its characteristics.

Optimum Properties
Optimum properties are achieved with small cross sections and rapid quenching in the solution treated and aged condition. Larger cross-section sizes or delayed quenching may result in suboptimal properties.
Hardness
Typical hardness: Rockwell C 30-34 in the annealed state and approximately Rockwell C 35-39 in the solution and aged condition.
Forgeability/Formability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube is masterfully forged at 1,750°F (954°C), with a final forging temperature set at 1,450°F (788°C). For optimal outcomes, a reduction of at least 35% is recommended, ensuring superior strength and durability.
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube poses challenges when forming at room temperature, even post-annealing. Thus, intense forming operations like bending or stretching are best conducted on annealed material at temperatures reaching up to 1,200°F (649°C) without altering its mechanical integrity. Creep forming is an ideal method for hot sizing or forming within the temperature range of 1,000 to 1,200°F (538 to 649°C).
Machinability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube can be precision-machined using techniques similar to those employed for austenitic stainless steels. This includes using slow speeds, high feeds, ensuring robust tool stability, and employing generous amounts of non-chlorinated cutting fluids for optimal machining performance.
Weldability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube exhibits excellent weldability in both annealed and solution-treated, partially aged conditions. The aging process is seamlessly achieved during post-weld heat treatment.
Special care must be taken to prevent contamination by oxygen, nitrogen, and hydrogen. Fusion welding should be 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 are feasible without a protective atmosphere.
Special Considerations
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube is susceptible to hydrogen contamination from improper pickling and may absorb oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. This contamination can adversely impact ductility, notch sensitivity, and formability, necessitating stringent quality control measures.
