What is the difference between Gr12 titanium plate and Gr2 titanium plate?

Gr2 titanium plate is a pure titanium plate with standard iron and oxygen content. Gr12 contains 0.3% molybdenum and 0.8% nickel and is a titanium alloy plate. It is a near-α titanium alloy developed to improve the crevice corrosion performance of pure titanium. The Mo and Ni components in the titanium alloy not only strengthen the mechanical properties of the alloy, but also are resistant to high temperatures, low PH values, chloride or weak reduction. The acid has good crevice corrosion performance, and its corrosion resistance is significantly better than pure titanium and close to GR7 titanium alloy. But the price is one-sixth of the GR7 titanium plate. Gr12 titanium alloy plate also has good process plasticity and welding performance, and has been widely used in the chemical industry.
