Products Description
Ti-0.3Mo-0.8Ni (Grade 12) alloy is a kind of low alloying Ti - Mo - Ni alloy which improves the crack corrosion performance of pure titanium. The alloy contains 0.5% Mo and 0.8% Ni, which not only strengthens the alloy, but also has good anti-crevice corrosion performance for high temperature, low PH chloride and weak reductive acid. Its corrosion resistance is significantly better than that of pure titanium and close to TA9 alloy. Ti-0.3Mo-0.8Ni alloy has been widely used in chemical industry. The alloy can be used in annealing. Its main products are titanium sheets, titanium rods, titanium tubes, forging and titanium wires.

Ti-0.3Mo-0.8Ni (Grade 12) Application
Ti-0.3Mo-0.8Ni alloy is widely used in the condition that the pure titanium can be corroded by cracks. The typical equipment includes heat exchanger for producing zinc chloride or hydrochloric acid vapor, stripper for bromine and vacuum salt production device.
