Production of caustic soda electrolysis of salt solution, hydrogen, chlorine and chlorine chlor-alkali products, industrial equipment, require high strength corrosion resistance. Chlor-alkali industry has major corrosive medium: saline and the cell within the medium, wet chlorine and inorganic acids, oxides, alkali. Common materials are super austenitic stainless steel, nickel and high nickel alloys, copper, titanium and other metal materials. Titanium chlor-alkali industry is the most important basic material, because the titanium chloride ion corrosion resistance than stainless steel and other nonferrous metals.
