Zirconium is a very corrosion resistant metal, used in chemical corrosion resistant equipment, its acid resistance volt than titanium and various steel, close to tantalum. Zirconium in all concentrations, temperatures up to above the boiling point of hydrochloric acid have the corrosion resistance, not easy to occur gap corrosion, pitting corrosion and stress corrosion, zirconium in sulfuric acid can be resistant to point boiling point and above the boiling point, the concentration of up to 70% Zirconium can certain highly corrosive environment including a variety of inorganic acids (hydrochloric acid, sulfuric acid, חומצה חנקתית, וכו '), alkalis, most organic acids (such as hydrochloric acid, formic acid, וכו ') a variety of salt solutions and molten alkali should be treated. The corrosion resistance in sodium hydroxide media is the same as that of nickel.
