Grade 12
Ti-Grade 12 ; It is a titanium alloy containing 0.30% Mo and 0.80% Ni.
Ti Grade 12 is similar to Grade 2 and Grade 3 titanium alloys but with the addition of Mo and Ni. It exhibits high strength, good heat and wear resistance, and excellent weldability. It also has high resistance to crevice corrosion in chloride-containing environments.
