Daxun Alloy's Premium Pure Titanium Grade 1 Tubes Include:
Seamless and welded titanium tubes, lauded for their exceptional ductility and cold formability, are perfect for deep drawing applications. Grade 1 titanium tubes are renowned for their superior general and seawater corrosion resistance, as well as their impressive resistance to oxidizing, neutral, and mildly reducing media, including chlorides.
Titanium's remarkable properties-low density (about half that of nickel-based alloys), high strength, lightweight nature, and corrosion resistance-make it an exemplary choice for challenging chemical environments. Adherence to rigorous standards: ASTM B338 | ASTM B265 | ASME SB265 | ASTM F67 | ISO 5832-2 | 3.7025 | UNS R50250 ensures unparalleled performance.
Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
Widely recognized as the industry standard, Grade 2 titanium tubes strike a perfect balance between moderate strength and reasonable ductility. They offer outstanding corrosion resistance in both highly oxidizing and mildly reducing environments, including chlorides. This makes them ideal for the chemical and offshore industries, as well as aircraft manufacturing, where strength and formability are crucial. Additionally, they are utilized in heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping systems.
Fabrication
Titanium Grade 2 exhibits excellent responsiveness to cold forming using standard techniques. Although machining is straightforward, maintaining sharp tools and liberal use of coolant are paramount. Similar to machining austenitic stainless steels, deep and continuous cuts with slow feeds and speeds are recommended.
Stock Availability
Daxun Alloys maintains a comprehensive inventory of CP 2 Grade Titanium Seamless and Welded Pipes, available in a wide array of sizes.
Weight Reduction
CP 2 grade titanium tubes, with their low density and excellent strength-to-weight ratio, are ideal for applications demanding weight reduction without compromising strength. They are cold formable and exhibit good ductility. Welding can be performed using conventional TIG and MIG processes, provided inert gas shielding is employed to prevent weld zone embrittlement.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tubes feature an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. Upon heating to approximately 885°C [1625°F], it transitions to a beta (body-centered cubic) structure. This transformation temperature varies with the type and quantity of impurities or alloying elements. Alloying additions also result in two temperature zones: the alpha transformation zone (all alpha) and the beta transformation zone (all beta), with a mixed alpha-beta phase in between. Typically, Grade 2 titanium's alpha and beta transformation temperatures 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 either hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. Ensuring continuous perimeters throughout manufacturing, the process encompasses multiple steps: sponge titanium vacuum arc melting, ingot blanking for hollow blanks, cleaning, cutting, 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.
