Daxun Alloy's pure titanium Grade 1 titanium tubes include:
Seamless titanium tubes and welded titanium tubes. These tubes boast excellent ductility and cold formability, making them perfect for deep drawing applications. Grade 1 titanium tubes are renowned for their superior general and seawater corrosion resistance. They exhibit excellent resistance to oxidizing, neutral, and slightly reducing media, including chlorides.
Titanium's low density, approximately half that of nickel-based alloys, combined with its high strength, light weight, and corrosion resistance, makes it an unparalleled choice for a variety of harsh chemical environments. 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)
Grade 2 titanium tubes are the preferred choice for industrial applications, offering an exceptional balance of moderate strength and excellent ductility. They provide remarkable corrosion resistance in highly oxidizing and slightly reducing conditions, including exposure to chlorides. Widely used in the chemical and offshore industries, as well as in aircraft manufacturing, these tubes offer the ideal combination of strength and formability. Additional applications include heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping systems.
Fabrication
Titanium Grade 2 is highly responsive to cold forming using standard methods. It can be machined with ease, provided that sharp tools are maintained and coolant is used liberally. Similar to the machining of austenitic stainless steels, deep and continuous cuts with slow feeds and speeds are recommended.
Stock Availability
Daxun Alloys maintains a wide inventory of CP 2 Grade Titanium Seamless and Welded Pipes, available in a variety of sizes to meet diverse application needs.
Weight Reduction
CP 2 grade titanium tubes offer a low density and a high strength-to-weight ratio, making them ideal for applications requiring significant weight reduction without compromising strength. These tubes are cold formable, possess good ductility, and can be welded using conventional TIG and MIG processes, although inert gas shielding is necessary to prevent weld zone embrittlement.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tubes exhibit an alpha (hexagonal close-packed) crystal structure, similar to commercially pure titanium grades 1 and 3. Around 885°C (1625°F), this structure transforms into a beta (body-centered cubic) form. The transformation temperature can be altered by varying impurities or alloying elements. Alloy additions create 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 transformation temperatures for Grade 2 titanium are 890°C (1635°F) for alpha and 913°C (1675°F) for beta.
Grade 2 Titanium Seamless Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium seamless tubes are crafted from hollow blanks through hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. Throughout manufacturing, tubes maintain continuous perimeters. The comprehensive manufacturing process includes: sponge titanium vacuum arc melting, ingot blanking to create hollow blanks, cleaning, cutting, feeding, hot extrusion or oblique rolling and piercing, degreasing, drying, cutting, online annealing, straightening, pickling, multiple cold rolling, degreasing, drying, vacuum annealing, straightening, cutting, final inspection, marking (DAXUN), and packaging.
Grade 2 Titanium Welded Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium welded pipe epitomizes quality and precision. Crafted from annealed flat-rolled steel plate or steel strip and leveraging state-of-the-art automatic arc welding (TIG) processes, this pipe undergoes a meticulous production journey: from titanium plate uncoiling, shearing, and butt welding, to cleaning, pipe forming, TIG welding, eddy current testing, pre-sizing, annealing, precision reducing and sizing, straightening, caliper marking, cutting, ultrasonic testing, hydrostatic testing, final inspection, and packaging. Each welded pipe is subjected to a mandatory stress relief heat treatment post-formation and welding, ensuring unparalleled durability and performance. Importantly, Daxun does not employ any filler materials during the welding process.
Introducing the premium Ti-6Al-4V Titanium Pipe - Grade 5 Titanium Tube
Titanium Alloy - (UNS R56400): The hallmark of innovation and strength.
Introduction to Daxun's Titanium Innovations.
Meet the DAXUN Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400), the titan among titanium alloys. This duplex alpha+beta titanium alloy synergizes aluminum as the alpha stabilizer and vanadium as the beta stabilizer. Renowned for its high strength, this alloy performs at temperatures as low as 800°F (427°C). Ideal for annealing, solution treating, and aging, the ATI Ti-6Al-4V, Grade 5 alloy is essential in applications demanding reliability and strength, such as compressor blades, disks, and rings for jet engines; fuselage and space capsule components; pressure vessels; *** cases; helicopter rotor hubs; fasteners; and critical forgings, delivering an exceptional strength-to-weight ratio.
The alloy's production begins with initial melting via vacuum arc (VAR), electron beam (EB), or plasma arc hearth melting (PAM), followed by remelting through one or two vacuum arc steps.
