Product Overview –Titanium Grade 2 Tubes
Titanium Grade 2 Tubes, are commercially pure titanium tubes renowned for their outstanding corrosion resistance, lightweight properties, excellent strength-to-weight ratio, and exceptional durability in highly aggressive environments. Designated as UNS R50400, Titanium Grade 2 is the most widely used commercially pure titanium alloy because it combines excellent formability, weldability, and corrosion resistance with moderate mechanical strength.
Titanium Grade 2 exhibits exceptional resistance to seawater, chlorides, oxidizing acids, hypochlorite solutions, wet chlorine, nitric acid, and numerous industrial chemicals. Its naturally forming oxide film provides superior protection against pitting, crevice corrosion, and general corrosion, even under severe operating conditions.
These tubes are extensively used in chemical processing plants, offshore oil & gas platforms, desalination plants, heat exchangers, condensers, marine engineering, aerospace, power generation, pharmaceutical manufacturing, pulp & paper industries, and pollution control systems.
