Titanium Grade 2 is light weight and highly corrosion resistant. It is an unalloyed titanium and is considered a “commercially pure” titanium (TiCP). Thanks to its varied usability and wide availability, Grade 2 is used in most of the chemical processing plants and is cold formable. Grade 2 plate and sheet can have ultimate tensile strength at and above 40,000 psi.
With moderate strength and excellent corrosion resistance, it also offers ductility and high impact toughness, and good weldability. It is used commonly in applications that require welding. Grades 2 is not hardenable by heat treatment.
Titanium Grade 5 is the most commonly used Titanium worldwide.
Titanium Grade 5 is alloyed with 6% Aluminum and 4% Vanadium and is commonly known as Ti 6Al-4V. Grade 5 or Ti 6Al-4V, accounts for 50 percent of total titanium usage the world over.
It can be heat treated to enhance mechanical properties. It can be used in welded fabrication at service temperatures of up to 315°C. This alloy offers high strength at a light weight, useful formability and high corrosion resistance.
