Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)

This is the most commonly used titanium tube for industrial applications, providing an exceptional balance of moderate strength and reasonable ductility. It offers outstanding corrosion resistance in both highly oxidizing and slightly reducing conditions, including chlorides. It ensures robust corrosion protection in the chemical and offshore industries, as well as aircraft manufacturing, where strength and ease of forming are essential. Furthermore, it is widely utilized in heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and pipes.

Fabrication

Titanium Grade 2 responds excellently to cold forming using standard methods. It can be readily machined, but special attention must be paid to maintaining sharp tools and the liberal use of coolant. Similar to machining austenitic stainless steels, cuts should be deep and continuous with slow feeds and speeds to ensure quality.

Stock Availability

Daxun Alloys stocks CP 2 Grade Titanium Seamless and Welded Pipes in a wide variety of sizes to meet all your requirements.

Weight Reduction

CP 2 grade titanium tubes possess low density and a high strength-to-weight ratio, making them ideal for applications that require weight reduction without compromising overall strength. These tubes are cold formable, exhibit good ductility, and can be welded using conventional TIG and MIG processes, though inert gas shielding is crucial to prevent embrittlement of the weld zone.

Crystal Structure

At room temperature, ASTM B338 Grade 2 titanium tube has an alpha (hexagonal close-packed) crystal structure similar to commercially pure titanium grades 1 and 3. Around 885°C (1625°F), it transforms into a beta (body-centered cubic) structure. This transformation temperature can vary depending on the impurities or alloying additions present. The addition of alloying elements divides the single equilibrium transformation temperature into two 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 crafted from hollow blanks via the hot extrusion process or oblique rolling and piercing process, followed by multiple cold rolling stages. The seamless tubes should maintain continuous perimeters at all stages of manufacturing. The comprehensive manufacturing process involves: 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 produced from annealed flat-rolled steel plate or steel strip using the automatic arc welding (TIG) process. The principal production stages include: 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 packaging. Welded pipes undergo at least one stress relief heat treatment after forming and welding. Daxun does not use 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 premier choice among titanium alloys. As a duplex alpha+beta titanium alloy, it incorporates aluminum as the alpha stabilizer and vanadium for beta stabilization. This high-strength alloy is remarkably versatile, maintaining performance at temperatures as low as 800°F (427°C). ATI Ti-6Al-4V, Grade 5 is ideally suited for annealing, solution treating, and aging processes. Its applications are extensive and include compressor blades, disks, and rings for jet engines; fuselage and space capsule components; pressure vessels; *** cases; helicopter rotor hubs; fasteners; and critical forgings demanding a superior strength-to-weight ratio.
The alloy's initial melting is conducted through advanced techniques such as vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM). Subsequent remelting is executed in one or two vacuum arc steps, ensuring the highest purity and consistency.
Specifications

Beta Transus Temperature is precisely 1830°F (± 25°); 999°C (± 14°), ensuring superior phase transformation characteristics.

Heat Treatment

For applications requiring high hardness, tensile strength, and fatigue resistance, the alloy is annealed at 1,700-1,900°F (927 - 1,038°C).
DAXUN 6-4 Grade 5 Titanium Tube offers diverse heat treatment methods for tailored performance.
1. Annealing: Conducted at 1,275 - 1,400°F (691 - 760°C) for ½ to 2 hours, followed by air or furnace cooling.
2. Stress Relief Annealing: Performed at 1,000 - 1,200°F (538 - 649°C) for 1 to 8 hours, with air or furnace cooling.
3. Solution Heat Treating: Applied at 1,675 - 1,750°F (913 - 954°C) for 1 hour, followed by water quenching for optimal results.
4. Aging: Implemented at 975 - 1,025°F (524 - 552°C) for 4 to 8 hours, with air cooling to achieve desired properties.

Optimum Properties

Achieving optimum properties requires rapid quenching of small cross sections in the solution treated and aged condition. Larger cross sections or delayed quenching may result in suboptimal characteristics.

Hardness

In the annealed state, typical hardness ranges from Rockwell C 30-34, whereas in the solution and aged condition, it ranges approximately from Rockwell C 35-39.

completed during post-weld heat treatment. Meticulous precautions are essential to prevent contamination from oxygen, nitrogen, and hydrogen. Fusion welding is best performed in an inert gas-filled chamber or with an inert gas tail shield covering the molten metal and surrounding hot zones. Additionally, spot welding, seam welding, and flash welding can be conducted without the necessity of a protective atmosphere.

Special Considerations

DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube is susceptible to contamination by hydrogen from improper pickling and by the absorption of oxygen, nitrogen, and carbon during processes like forging, heat treating, and brazing. This contamination could detrimentally impact ductility, notch sensitivity, and formability.
