Titanium Gr. 23.7034 – UNS R50400 – Ti50A

Titanium equipment is often used in severe corrosive environments encountered in the chemical processing industries. Titanium has been considered an exotic wonder metal by many people. This was particularly true in reference to castings. However, increasing demands and rapidly advancing technology have permitted titanium castings to be commercially available at an economical cost. The combination of its cost, strength, corrosion resistance, and service life in very demanding corrosive environments suggest its selection in applications where titanium castings have never been considered in the past. Grade 2 is an unalloyed Titanium, with standard oxygen and medium strength.

General characteristics

The outstandings mechanical and physical properties of titanium, combined with its unexpected corrosion resistance in many environments
makes it an excellent choice for particularly aggressive environments like wet chlorine, chlorine dioxide, sodium and calcium hypochlorite,
chloride salt solutions, nitric acid and chromic acid. It also has exceptional resistance to most chlorinated hydrocarbons and organic acids
except oxalic and formic acids. The corrosion rate of titanium in formic acid may be reduced significantly by the adition of an oxidizing salt
such as ferric or cupric chloride.
