Overview of zirconium products
Zirconium Products
Zirconium is a rare metal, the price is relatively expensive, but because of its unique physical and chemical corrosion resistance, in the nuclear industry, aerospace, aviation and civil chemical industry and other fields of application has irreplaceable and excellent cost performance is widely used in special harsh process pipeline control, to ensure the safe and long-term process pipeline, stable and reliable operation. In civil industry, zirconium material has excellent corrosion resistance of oxidation resistance medium and reducing medium, especially reducing hydrochloric acid and sulfuric acid, phosphoric acid and acetic acid with stability above 100 ℃, and has incomparable excellent corrosion resistance of other materials such as titanium alloy, nickel and nickel alloy. Its corrosion resistance is one to several grades higher than that of nickel alloy, and is widely used in severe corrosion conditions.
Corrosion resistance characteristics and applications of zirconium and zirconium alloy products
Commonly used zirconium and zirconium alloy materials are: Zirconium702, Zirconium705
■ In all concentrations, temperatures up to higher than the boiling point of hydrochloric acid, have excellent corrosion resistance, not easy to happen crevice corrosion, corrosion and stress corrosion;
■ In sulfuric acid can be resistant to boiling point, and higher than the boiling point, the concentration of less than 70% of the sulfuric acid medium;
■ In acetic acid can be resistant to 250 ℃ below the various concentrations of acetic acid medium, its almost no corrosion;
■ In various concentrations of alkali solution and molten alkali medium is a unique corrosion resistant material;
■ Very good corrosion resistance in organic acids.
