Daxun Alloy's Pure Titanium Grade 1 Tubes Include:
Seamless titanium tubes and welded titanium tubes, renowned for their exceptional ductility and cold formability, making them perfect for deep drawing applications. Grade 1 titanium tubes are celebrated for their outstanding general and seawater corrosion resistance, as well as their excellent resistance to oxidizing, neutral, and slightly reducing media (solutions), even in the presence of chlorides.
With its low density-approximately half that of nickel-based alloys-high strength, lightweight, and unparalleled corrosion resistance, titanium is the optimal choice for enduring harsh chemical environments. Our products adhere to stringent standards: 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 commonly utilized titanium tube for industrial purposes, Grade 2 offers an ideal combination of moderate strength and impressive ductility. It boasts excellent corrosion resistance in both highly oxidizing and slightly reducing conditions, including chlorides. Perfect for the chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping, where both strength and ease of forming are paramount.
FabricationTitanium Grade 2 readily adapts to cold forming using standard techniques. It is highly machinable, though maintaining sharp tools and liberal coolant usage is crucial. Similar to austenitic stainless steels, machining requires deep, continuous cuts at slow feeds and speeds.Stock AvailabilityDaxun Alloys maintains a robust inventory of CP 2 Grade Titanium Seamless and Welded Pipes in various sizes to meet your needs.Weight ReductionCP 2 grade titanium tubes are prized for their low density and high strength-to-weight ratio, making them ideal for applications demanding weight reduction without compromising strength. These tubes are cold formable, exhibit good ductility, and can be welded using standard TIG and MIG processes, provided inert gas shielding is used to prevent weld zone embrittlement.Crystal StructureAt ambient temperature, ASTM B338 Grade 2 titanium tubes exhibit an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. Around 885°C [1625°F], this structure transitions to a beta (body-centered cubic) form. The transformation temperature can vary with impurities or alloying additions, which can also segment the equilibrium transformation into alpha and beta zones: the alpha transformation zone (below which the alloy is all alpha) and the beta transformation zone (above which it is all beta). Between these zones, both alpha and beta forms coexist. Typical 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 meticulously crafted from hollow blanks using hot extrusion or oblique rolling and piercing processes, followed by several cold rolling stages. Throughout manufacturing, the tubes maintain continuous perimeters. The comprehensive manufacturing process encompasses: sponge titanium vacuum arc melting, ingot blanking to obtain hollow blanks, cleaning, cutting and feeding, hot extrusion or oblique rolling with piercing, degreasing, drying, cutting, online annealing and straightening, pickling, multiple cold rolling cycles, degreasing, drying, vacuum annealing, straightening, cutting, pickling, final inspection, marking (DAXUN), and packaging.Grade 2 Titanium Welded Pipe Manufacturing ProcessDaxun's ASTM B338 Grade 2 titanium welded pipe is crafted from annealed flat-rolled steel plate or steel strip, utilizing an advanced automatic arc welding (TIG) process. The meticulous production processes 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 packaging. Post-formation and welding, these welded pipes undergo at least one stress relief heat treatment. Notably, 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's Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400), stands as the quintessential titanium alloy, revered for its duplex alpha+beta structure. Aluminum serves as the alpha stabilizer while vanadium functions as the beta stabilizer. This high-strength alloy thrives at low temperatures of approximately 800°F (427°C). The ATI Ti-6Al-4V, Grade 5 alloy is ideally suited for annealing, solution treating, and aging. Its applications span a broad spectrum, including compressor blades, disks, and rings for jet engines; fuselage and space capsule components; pressure vessels; *** cases; helicopter rotor hubs; fasteners; and critical forgings characterized by a high strength-to-weight ratio.
Initially, the alloy is melted using sophisticated methods such as vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM). Remelting occurs through one or two vacuum arc stages.
Specifications
• ASTM B338 - Standard Heat Treatable Titanium Tube
• AMS 4928 - Forgings and Forging Stock (Annealed)
• AMS 4965 - Forgings (Solution Treated and Aged)
• AMS 4967 - Forgings (Annealed, Heat Treatable)
Physical Properties
Ti-6Al-4V Titanium Tube Melting Range: 2,800-3,000°F (1,538 - 1,649°C)
Density: 0.160 lb/in³; 4.47 g/cm³
Beta Transus Temperature: 1830°F (± 25°); 999°C (± 14°)
Heat Treatment
For applications demanding high hardness, tensile strength, and fatigue strength, the titanium tube is annealed at 1,700-1,900°F (927 - 1,038°C).
The versatile DAXUN 6-4 Grade 5 Titanium Tube can undergo various heat treatment processes.
1. Annealing: 1,275 -1,400°F; (691 - 760°C), ½ to 2 hours, cooled by air or furnace.
2. Stress Relief Annealing: 1,000 -1,200°F; (538 - 649°C), for 1 to 8 hours, followed by air or furnace cooling.
3. Solution Heat Treating: 1,675 -1,750°F; (913 - 954°C), maintaining for 1 hour, then water quenching.
4. Aging: 975 -1,025°F; (524 - 552°C), sustained for 4 to 8 hours, then air cooling.
Optimum Properties
Achieving optimal properties involves rapid quenching for small cross sections in the solution treated and aged condition. Conversely, larger cross-section sizes and/or delayed quenching might yield less optimal properties.
Hardness
In the annealed state, the typical hardness ranges between Rockwell C 30-34, increasing to Rockwell C 35-39 in the solution treated and aged state.
Forgeability/Formability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube is masterfully forged at an intense 1,750°F (954°C) and achieves its final form at 1,450°F (788°C). For unparalleled results, a reduction of at least 35% is strongly recommended.
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube presents challenges when formed at room temperature, even after annealing. This makes it ideal for severe forming operations such as bending or stretching, which can be executed on the annealed material at temperatures soaring up to 1,200°F (649°C) without altering its mechanical properties. Hot sizing or forming can be effectively performed through creep forming at temperatures ranging from 1,000 to 1,200°F (538 to 649°C).
Machinability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube can be precisely machined using methods akin to those for austenitic stainless steels. Optimal results are achieved with slow speeds, high feeds, robust tool rigidity, and the application of copious amounts of non-chlorinated cutting fluids.
Weldability
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube boasts excellent weldability in either the annealed or solution and partially aged conditions, with aging
completed during post-weld heat treatment. It is imperative to avoid contamination from oxygen, nitrogen, and hydrogen. Fusion welding should be performed in an inert gas-filled chamber, or with an inert gas tail shield over the molten metal and adjacent hot zones. Techniques such as spot welding, seam welding, and flash welding can be carried out without the necessity of a protective atmosphere.
Special Considerations
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 Titanium Tube must be safeguarded against contamination from hydrogen due to improper pickling and the absorption of oxygen, nitrogen, and carbon during processes such as forging, heat treating, and brazing. Such contamination can diminish ductility and negatively impact notch sensitivity and formability.FAQ Q1: What products can you offer?
