Daxun Alloy's Pure Titanium Grade 1 Tubes Include:
Seamless Titanium Tubes and Welded Titanium Tubes, which offer remarkable ductility and cold formability, making them perfect for deep drawing. These Grade 1 Titanium Tubes are renowned for their excellent general and seawater corrosion resistance, as well as superb resistance to oxidizing, neutral, and slightly reducing media (including chlorides).
Titanium's low density (about half that of nickel-based alloys), combined with its high strength, light weight, and corrosion resistance, makes it an outstanding choice for a range of harsh chemical environments. Our 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 frequently used titanium tube for industrial applications, offering a superb balance of moderate strength and excellent ductility. It provides outstanding corrosion resistance in both highly oxidizing and slightly reducing environments (including chlorides). It is ideal for applications in the chemical and offshore industries, as well as aircraft manufacturing, where strength and formability are essential. Additionally, it is utilized in heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping systems.
Fabrication
Titanium Grade 2 responds exceptionally well to cold forming using standard methods. While it can be readily machined, it is crucial to maintain sharp tools and use liberal amounts of coolant. Similar to machining austenitic stainless steels, cuts should be deep and continuous with slow feeds and speeds.
Stock Availability
Daxun Alloys stocks CP 2 Grade Titanium Seamless and Welded Pipes available in a variety of sizes, ready to meet your specific requirements.
Weight Reduction
CP 2 Grade Titanium Tubes offer low density and a high strength-to-weight ratio, making them ideal for applications where weight reduction is a priority without compromising strength. They are cold formable, have good ductility, and can be welded using conventional TIG and MIG processes, although inert gas shielding is necessary to prevent embrittlement of the weld zone.
Crystal Structure
At room temperature, ASTM B338 Grade 2 Titanium Tube features 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 be adjusted depending on the type and quantity of impurities or alloying elements. The addition of alloying elements also divides the single transformation temperature into two distinct 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 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 precision-manufactured from hollow blanks using hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. The seamless tubes maintain continuous perimeters throughout all manufacturing stages. The production process includes: sponge titanium vacuum arc melting, ingot blanking to create 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 premium ASTM B338 Grade 2 Titanium Welded Pipe is crafted from top-tier annealed flat-rolled steel plate or steel strip using the advanced automatic arc welding (TIG) process. Our meticulous production phases encompass 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 meticulous packaging. Each welded pipe undergoes at least one stress-relief heat treatment post-formation and welding. At Daxun, we ensure no filler materials are used during the welding process, guaranteeing unparalleled quality and integrity.
Ti-6Al-4V Titanium Pipe - Exquisite Grade 5 Titanium Tube
Titanium Alloy - (UNS R56400) - Exemplifying Excellence
Introduction
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400) stands as the epitome of titanium alloys. This duplex alpha+beta alloy, bolstered by aluminum as the alpha stabilizer and vanadium as the beta stabilizer, boasts formidable strength. Capable of enduring low temperatures of approximately 800°F (427°C), the ATI Ti-6Al-4V, Grade 5 alloy is indispensable for annealing, solution treating, and aging. Its applications span crucial aerospace 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, making it a cornerstone of modern engineering.
The alloy's initial melting is performed using cutting-edge techniques such as vacuum arc remelting (VAR), electron beam (EB) melting, or plasma arc hearth melting (PAM). Subsequent remelting is conducted through one or two vacuum arc steps, ensuring supreme purity and consistency.

Heat Treatment
Annealed at 1,700-1,900°F (927 - 1,038°C), our titanium tubes achieve exceptional hardness, tensile strength, and fatigue resistance.
The DAXUN 6-4 Grade 5 Titanium Tube can undergo a diverse array of heat treatments to meet specific requirements.
1. Annealing: Conducted at 1,275 -1,400°F (691 - 760°C) for ½ to 2 hours, followed by air or furnace cooling to ensure structural integrity.
2. Stress Relief Annealing: Performed at 1,000 -1,200°F (538 - 649°C) for durations ranging from 1 to 8 hours, then air or furnace cooled to relieve internal stresses.
3. Solution Heat Treating: Executed at 1,675 -1,750°F (913 - 954°C) for 1 hour, followed by a rapid water quench to achieve desired mechanical properties.
4. Aging: Carried out at 975 -1,025°F (524 - 552°C) for 4 to 8 hours, with subsequent air cooling to enhance material toughness.
Optimum Properties
Optimal properties are achieved with small cross sections through rapid quenching in the solution treated and aged condition. Larger cross-section sizes and/or delayed quenching may result in suboptimal properties.
Hardness

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), concluding at 1,450°F (788°C). For superior results, we advocate a reduction of no less than 35%.
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube presents challenges in forming at room temperature, even post-annealing. Therefore, intense forming processes such as bending or stretching can be executed on annealed material at temperatures up to 1,200°F (649°C) without compromising its mechanical properties. For hot sizing or forming, creep forming is ideal 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 expertly machined using methods suitable for austenitic stainless steels. Employing slow speeds, high feeds, robust tool rigidity, and substantial quantities of non-chlorinated cutting fluids ensures optimal results.
Weldability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube demonstrates excellent weldability in both annealed and solution-treated, partially aged conditions, with subsequent aging achieved during post-weld heat treatment.
Post-weld heat treatment must be managed carefully to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be conducted in an inert gas-filled chamber or with an inert gas tail shield to protect the molten metal and adjacent hot zones. Additionally, spot welding, seam welding, and flash welding can be performed without the need for a protective atmosphere.
Special Considerations
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube requires vigilant management to avoid contamination with hydrogen through improper pickling, and the absorption of oxygen, nitrogen, and carbon during forging, heat treating, brazing, and other processes. Such contamination can reduce ductility, impair notch sensitivity, and compromise formability.
