Since Titanium metal first became a commercial reality in 1950, corrosion resistance has been an important consideration in its selection as an engineering structural material. Combination of high strength and low density results in making Titanium superior to almost all other metals and become a standard metal for diverse applications.
Titanium and its alloys provide excellent resistance to general localized attack under most oxidizing, neutral and inhibited reducing conditions. They also remain passive under mildly reducing conditions.
The corrosion resistance of Titanium to moist chlorine gas and chloride containing solutions is the basis for the largest number of titanium applications. Titanium is widely used in chlor-alkali cells, dimensionally stable anodes, bleaching equipment for pulp and paper, heat exchangers, pumps, piping and vessels used in the production of organic intermediates, pollution control devices, and even for human body prosthetic devices.
Titanium is fully resistant to solutions of chlorites, hypochlorites, chlorates, perchlorates and chlorine dioxide. Titanium equipment has been used to handle these chemicals in the pulp and paper industry for many years with no evidence of corrosion. Titanium is used today in nearly every piece of equipment handling wet chlorine or chlorine chemicals in a modern bleach plant, such as chlorine dioxide mixers, piping, and washers.
Titanium has excellent resistance to corrosion by neutral chloride solutions even at relatively high temperatures. Titanium generally exhibits very low corrosion rates in chloride environments.
The resistance of titanium to bromine and iodines is similar to its resistance to chlorine. It is attacked by the dry gas but is passivated by the presence of moisture. Titanium is reported to be resistant to bromine water.
Titanium has been extensively utilized for handling and producing nitric acid in applications where stainless steels have exhibited significant uniform or intergranular attack.
Titanium is highly resistant to corrosion by inorganic salt solutions. Corrosion rates are generally very low at all temperatures to the boiling point.
