Titanium Grade 12 is similar to Grade 2 and Grade 3 except Grade 12 has the addition of Mo and Ni. These additions to Grade 12 offer a lower cost option than the Palladium bearing grades. Grade 12 has high strength, good heat and wear resistance and is highly weldable. Grade 12 is used for Chemical Processing, Power generation, Desalination, Marine Hydrocarbon processing and Mining
