Grade 7 (Gr7) is a palladium-bearing titanium alloy (Ti-0.2Pd) with the same mechanical and physical properties as commercially pure titanium Gr2, but with significantly enhanced crevice corrosion resistance in reducing acids, brine, and high-temperature corrosive environments. It is widely used in chemical processing, desalination, oil & gas, and industrial equipment requiring extreme corrosion stability.
