Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
This versatile titanium tube is the most frequently used in industrial applications, offering a superb balance of moderate strength and reasonable ductility. It excels in corrosion resistance under both highly oxidizing and slightly reducing conditions (including chlorides). Grade 2 titanium tubes are ideal for chemical and offshore industries, aircraft manufacturing, 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 amenable to cold forming using standard techniques. It can be easily machined, though careful 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.

Weight Reduction
CP 2 Grade Titanium Tubes: With a low density and a high strength-to-weight ratio, these tubes are perfect for applications demanding weight reduction without compromising strength. They offer excellent cold formability, good ductility, and can be welded using conventional TIG and MIG processes, with inert gas shielding required 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, akin to commercially pure titanium grades 1 and 3. At approximately 885°C [1625°F], it transforms to a beta (body-centered cubic) structure. This transformation temperature can vary depending on the type and amount of impurities or alloying additions. The addition of alloying elements also divides the equilibrium transformation temperature into two distinct zones: the alpha transformation zone, below which the alloy is entirely alpha, and the beta transformation zone, above which the alloy is entirely 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 using either the hot extrusion process or the oblique rolling and piercing process, followed by multiple cold rolling processes. Throughout the manufacturing operation, the tubes maintain continuous perimeters. The creation of titanium seamless tubes involves: sponge titanium vacuum arc melting, ingot blanking to obtain hollow blanks, cleaning, cutting and feeding, hot extrusion, or oblique rolling with piercing, followed by degreasing, drying, cutting, online annealing and straightening, pickling, multiple cold rolling, degreasing, drying, vacuum annealing, straightening, cutting, pickling, final inspection, marking (DAXUN), and packaging.
