In many cases, data were obtained in the laboratory. Actual in-plant environments often contain impurities which can exert their own effects. Heat transfer conditions or unanticipated deposited residues can also alter results. Such factors may require in-plant corrosion tests. A tabulation of available general corrosion data is given in the Appendix.
Titanium offers outstanding resistance to a wide variety of environments.
As always, this information should only be used as a guideline. 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, although they may be attacked by strongly reducing or complexing media. Titanium metal's corrosion resistance is due to a stable, protective, strongly adherent oxide film. This film forms instantly when a fresh surface is exposed to air or moisture.
