Waste water and exhaust gas treatment in the chemical industry requires very high corrosion resistance of the material, and Gr2 titanium alloy has excellent performance in this regard, so this titanium alloy has been widely used in chemical containers, fertilizer industry, oil refining industry and so on. Due to its good corrosion resistance, light weight and high temperature resistance, Gr2 titanium alloy is widely used in the difficult parts of submarine and land petroleum exploitation industrial fields, such as deep-sea drilling platforms, pipelines, pumps, packings and heat exchangers.
