Daxun Alloy's Pure Titanium Grade 1 Titanium Tubes Include:
Seamless titanium tubes and welded titanium tubes, both of which exhibit exceptional ductility and cold formability, making them perfect for deep drawing applications. Grade 1 titanium tubes are celebrated for their excellent resistance to general corrosion, seawater corrosion, and their exceptional performance in oxidizing, neutral, and slightly reducing media (solutions), including chlorides.
Titanium's low density-approximately half that of nickel-based alloys-combined with its high strength, light weight, and remarkable corrosion resistance, makes it an outstanding choice for various harsh chemical conditions. 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)
This titanium tube is the go-to choice for industrial applications, offering a superb balance of moderate strength and reasonable ductility. It provides outstanding corrosion resistance in both highly oxidizing and slightly reducing environments, including chlorides. Grade 2 titanium tubes are essential in the chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, and CPI equipment. They are also utilized for industrial and aerospace components and pipes where strength and ease of forming are critical.
Fabrication
Titanium Grade 2 responds exceptionally well to cold forming using standard methods. It can be readily machined, but it is crucial to maintain sharp tools and use liberal amounts of coolant. As with machining austenitic stainless steels, the cuts should be deep and continuous with slow feeds and speeds.
Stock Availability
Daxun Alloys stocks CP 2 Grade Titanium Seamless and Welded Pipes in an extensive range of sizes.
Weight Reduction
CP 2 grade titanium tubes boast a low density and a high strength-to-weight ratio, making them ideal for applications where weight reduction is critical without compromising overall strength. They are cold formable, exhibit good ductility, and can be welded using conventional TIG and MIG processes, although inert gas shielding is necessary to prevent embrittlement in the weld zone.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tubes possess an alpha (hexagonal close-packed) crystal structure, similar to commercially pure titanium grades 1 and 3. At approximately 885°C [1625°F], they transform into a beta (body-centered cubic) structure. This transformation temperature can vary depending on the type and quantity of impurities or alloying additions. The addition of alloying elements divides the single transformation temperature into two zones: the alpha transformation zone, where the alloy is all alpha, and the beta transformation zone, where the alloy is all beta. Between these two temperatures, both alpha and beta phases 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 meticulously crafted from hollow blanks through a hot extrusion process or an oblique rolling and piercing process, followed by multiple cold rolling processes. The seamless tubes maintain continuous perimeters at every stage of the manufacturing operation.
