Commercially pure titanium is available in grades 2 and 4 (at least 99% titanium). The chemical makeup of each grade varies somewhat, which has an impact on mechanical qualities and design potential. Both grades share a similar level of corrosion resistance. Titanium is very corrosion resistant, lightweight, and frequently outperforms stainless steels in most conditions in terms of corrosion resistance. Grade 2 is the preferred alloy for the majority of industrial applications that call for good ductility and corrosion resistance out of the four commercially pure (C.P.) titanium grades.
It has excellent corrosion resistance to:
Titanium alloys are used extensively in the medical and aerospace industries. Titanium Grade 2 is highly suited for use in the marine, chemical processing, and desalination industries due to its strength and corrosion resistance. Applications for Grade 2 titanium often include flue-gas desulphurization systems, reaction and pressure vessels, heat exchangers, liners, tubing or piping systems, oil and gas components, and many other industrial parts. Temperatures for continuous service can reach up to 800°F, and for sporadic, intermittent service, they can reach up to 1000°F.
