Compliance with standards includes: 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 prevalent titanium tube in industrial applications, Grade 2 offers a perfect blend of moderate strength and commendable ductility. It provides excellent corrosion resistance in both highly oxidizing and mildly reducing conditions, including chlorides. This tube is ideal for applications in the chemical and offshore industries, aircraft manufacturing, and more, where both strength and ease of forming are essential. Typical uses include heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and pipes.
Fabrication
Titanium Grade 2 is highly responsive to cold forming using standard methods. It can be easily machined with some precautions-maintain sharp tools and use ample coolant. Similar to machining austenitic stainless steels, machining should involve deep and continuous cuts with slow feed rates and speeds.
Stock Availability
Daxun Alloys maintains an extensive stock of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes.
Weight Reduction
CP 2 grade titanium tubes boast a low density and a 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 processes, with inert gas shielding necessary 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. At approximately 885°C (1625°F), it transitions to a beta (body-centered cubic) structure. This transformation temperature can be modified depending on impurities or alloying elements, which also split the single equilibrium transformation temperature into two zones: the alpha zone (below which the alloy is all alpha) and the beta 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) and 913°C (1675°F).
Grade 2 Titanium Seamless Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium seamless tubes are crafted from hollow blanks using a hot extrusion or oblique rolling and piercing process, followed by multiple cold rolling stages. Throughout the manufacturing process, titanium seamless tubes must maintain continuous perimeters. The production process includes: vacuum arc melting of sponge titanium to form ingots, 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 stages, degreasing, drying, vacuum annealing, straightening, cutting, pickling, final inspection, marking (DAXUN), and packaging.
Grade 2 Titanium Welded Pipe Manufacturing Process
Crafted with precision, Daxun's ASTM B338 Grade 2 titanium welded pipe is an epitome of excellence, manufactured from annealed flat-rolled steel plates or strips using the advanced automatic arc welding (TIG) process. The comprehensive production workflow includes: uncoiling, shearing, butt welding, cleaning, pipe forming, TIG welding, eddy current testing, pre-sizing, annealing, precision reducing, sizing, straightening, eddy current testing, caliper marking, cutting, ultrasonic testing, hydrostatic testing, final inspection, and packaging. Post-welding, each pipe undergoes a mandatory stress relief heat treatment to ensure superb quality and durability. Notably, Daxun's stringent welding process employs filler materials, guaranteeing impeccable welded joints.
Ti-6Al-4V Titanium Pipe - Grade 5 Titanium TubeTitanium Alloy - (UNS R56400)
Introduction
Presenting DAXUN's hallmark product: the Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400). Esteemed as the most sought-after titanium alloy, this duplex alpha+beta alloy integrates aluminum for alpha stabilization and vanadium for beta stabilization. Renowned for its extraordinary strength-to-weight ratio, this alloy thrives in temperatures around 800°F (427°C). ATI Ti-6Al-4V, Grade 5 alloy is versatile, ideal for annealing, solution treating, and aging. Its high strength makes it indispensable for jet engine compressor blades, disks, rings, fuselage, space capsule components, pressure vessels, *** casings, helicopter rotor hubs, fasteners, and critical high-strength forgings.
This superior titanium alloy undergoes initial melting through vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM). The remelting phase utilizes one or two vacuum arc steps to ensure purity and performance.
