Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
Our Grade 2 Titanium Tubes are the industry standard for a myriad of applications. Known for their balanced blend of moderate strength and impressive ductility, these tubes exhibit unparalleled corrosion resistance in both highly oxidizing as well as mildly reducing environments, such as those containing chlorides. Ideal for chemical processing, offshore installations, and aerospace projects, they deliver superior performance where both strength and formability are paramount. Additionally, they are extensively used in heat exchangers, hypochlorite systems, fire and ballast water systems, industrial components, CPI equipment, and piping solutions.
Fabrication
Titanium Grade 2 is highly responsive to standard cold forming techniques. It can be machined with ease, provided meticulous attention is given to maintaining sharp tools and applying liberal amounts of coolant. Similar to working with austenitic stainless steels, machining operations should involve deep, uninterrupted cuts at low feed rates and speeds for optimal results.

Weight Reduction
CP 2 grade titanium tubes stand out due to their low density and high strength-to-weight ratio, making them ideal for applications demanding weight reduction without compromising strength. They are easily cold formable, exhibit excellent ductility, and are weldable using standard TIG and MIG techniques. However, inert gas shielding is essential to prevent weld zone embrittlement.
Crystal Structure
At ambient temperatures, our ASTM B338 Grade 2 Titanium Tubes feature an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. Upon reaching around 885°C (1625°F), this structure transitions to beta (body-centered cubic). The transformation temperature can be altered based on impurities or alloying elements. Alloy additions also create distinct alpha and beta transformation zones, with typical temperatures for grade 2 titanium at 890°C (1635°F) for alpha and 913°C (1675°F) for beta.
