Description	Ti-Grade 7: Unalloyed titanium + 0.12 % to 0.25 % Pd, standard oxygen,

Special properties	Low-alloy titanium materials were mainly developed for use in the chemical industry. They offer the same excellent properties as pure titanium grades together with improved corrosion resistance. This is achieved by means of minor additions of Pd and Ni + Mo, which raise their resistance to reducing solutions and reduce their susceptibility to crevice corrosion, especially in chloride-containing media.
