Gr12 Titanium (Ti-0.3Mo-0.8Ni) Titanium alloy is a corrosion-resistant titanium alloy, a near-alpha alloy developed to improve the crevice corrosion performance of pure titanium. The alloy is strengthened, and it has good crevice corrosion resistance to high temperature, low pH chloride or weakly reducing acid, and its corrosion resistance is significantly better than pure titanium and close to Gr9 alloy. Gr12 alloy also has good process plasticity and welding performance, and has been widely used in the chemical industry. The alloy can be used in the annealed state.
Density 4.54g / m3, room temperature elastic modulus 103 ~ 107GPa, hardness HB180 ~ 215, phase transition point 890 ± 15 ℃.
Corrosion resistance: Nickel improves the crevice corrosion resistance of titanium in hydrochloric acid solution, but in reducing acid, the corrosion resistance of Ti-Ni alloy is lower than pure titanium. The proper addition of molybdenum to Ti-Ni alloy can improve its corrosion resistance in reducing medium.
