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

Titanium Alloys - Ti0.3Mo0.8Ni Grade 12

 
 

Chemical Formula

Ti0.3Mo0.8Ni

Background

Highly weldable, near alpha titanium alloy exhibiting improved strength and optimum ASMA code design allowables at increased temperatures, combined with superior crevice corrosion resistance and excellent resistance under oxidising to mildly reducing conditions, especially chlorides.
