CP Grade 12

Common Name
Titanium Grade 12
Ti-CODE 12™
Ti-0.3Mo-0.8Ni
UNS
R53400
General Information
“Titanium Alloy Grade 12 is lightly alloyed near-alpha alloy offering improved strength at elevated temperatures and optimum ASME Code design allowables. The material is readily weldable, and has superior crevice corrosion resistance. This material is very corrosion resistant in highly oxidizing and mildly reducing environments. The alloy is available as wire, plate, sheet, strip, forgings, bar, and billet.”
