Discover Daxun Alloy's premier pure titanium Grade 1 titanium tubes, featuring:
A choice of seamless or welded titanium tubes, renowned for their exceptional ductility and cold formability, making them ideal for deep drawing applications. Grade 1 titanium tubes offer outstanding general and seawater corrosion resistance, as well as excellent resistance to oxidizing, neutral, and mildly reducing media, including chlorides.
With its low density (approximately half that of nickel-based alloys), high strength, lightweight, and remarkable corrosion resistance, titanium is the material of choice for myriad demanding chemical conditions. Our execution standards are: 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)
Our most widely-used titanium tube for industrial applications, Grade 2 offers a superb balance of moderate strength and excellent ductility. It excels in highly oxidizing and slightly reducing conditions, including chlorides, and provides superior corrosion resistance in chemical and offshore industries, as well as aircraft manufacturing. It is also ideal for use in heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and pipes.
Fabrication
Titanium Grade 2 is well-suited for cold forming with standard methods. It can be machined efficiently with sharp tools and liberal coolant use. When machining, it is essential to take deep, continuous cuts with slow feeds and speeds, similar to working with austenitic stainless steels.
Stock Availability
Daxun Alloys maintains an extensive inventory of CP 2 Grade Titanium Seamless and Welded Pipes in diverse sizes to meet your needs.
Weight Reduction
CP 2 grade titanium tubes feature a low density and high strength-to-weight ratio, making them perfect for applications requiring weight reduction without compromising strength. These tubes are cold formable, exhibit good ductility, and can be welded using conventional TIG and MIG methods, provided inert gas shielding is employed to prevent weld zone embrittlement.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tube boasts an alpha (hexagonal close-packed) crystal structure, similar to commercially pure titanium grades 1 and 3. Around 885°C (1625°F), it undergoes a transformation to a beta (body-centered cubic) structure. Alloying elements can adjust this transformation temperature, dividing it into two zones: the alpha transformation zone (below which the alloy is all alpha) and the beta transformation zone (above which the alloy is all beta). In between, 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 crafted from hollow blanks via hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. These seamless tubes maintain continuous perimeters throughout manufacturing. The detailed process includes: sponge titanium vacuum arc melting, ingot blanking to obtain hollow blanks, cleaning, cutting and feeding, hot extrusion or oblique rolling plus 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 strips, employing a state-of-the-art automatic arc welding (TIG) process. The meticulous production stages include: uncoiling titanium plates, 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. To ensure superior quality, our welded pipes undergo at least one stress relief heat treatment post-forming and welding. Note: Daxun refrains from using any filler materials during the welding process.
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 preeminent titanium alloy. This duplex alpha+beta titanium alloy leverages aluminum as the alpha stabilizer and vanadium as the beta stabilizer. Renowned for its high-strength, it operates efficiently at temperatures as low as 800°F (427°C). The ATI Ti-6Al-4V, Grade 5 alloy is tailored for applications including annealing, solution treating, and aging. Its versatility is showcased in usages such as compressor blades, disks, and rings for jet engines; fuselage and space capsule parts; pressure vessels; *** cases; helicopter rotor hubs; fasteners; and critical forgings demanding an exceptional strength-to-weight ratio.
The alloy begins with initial melts using vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM). The remelting process is conducted in one or two vacuum arc steps to ensure impeccable purity.
