Pure Titanium Gr2 Tube
Titanium Grade 2 ERW tubing has a unique tendency to exceed the corrosion resistance of stainless steel in most environments. Of the four commercially available grades of pure or CP titanium, Gr 2 titanium heat exchanger tubing is considered to be the ideal alloy choice for most industrial applications requiring properties such as good ductility and corrosion resistance.
Description
Titanium Gr 2 sanitary tubing also offers excellent resistance to seawater and marine atmospheric corrosion. A much appreciated feature of Titanium Gr 2 Cold Rolled Coil is its light weight, due to its low density. This lower density makes Gr 2 Titanium Bright Annealed Tubing ideal, especially in applications where weight may be an area of concern.
Equivalent Grades of Titanium Grade 2 (UNS R50400)
Titanium Grade 2 is the most widely used commercially pure titanium (CP Titanium) grade. It is recognized by different designation systems worldwide while maintaining similar chemical composition and mechanical properties.

The medical and aerospace industries are two key sectors where there is a high demand for seamless titanium grade 2 tubing. the strength and corrosion resistance of grade 2 turned titanium alloys also make them well suited for applications in the marine, chemical processing, and desalination industries. Typically, CP Grade 2 titanium tubing is used in a variety of equipment including oil and gas components, linings, reaction and pressure vessels, piping systems, heat exchangers, flue gas desulfurization systems, and many other industrial components. Titanium Grade 2 tubing is available in continuous service temperatures up to 800°F, with occasional intermittent service temperatures up to 1,000°F.
