Zirconium Plug Valves

Zirconium is an expensive corrosion-resistant metal material with excellent resistance to corrosion by acids and alkalis. In some media, it even exceeds metals with good corrosion resistance such as niobium and titanium. Zirconium alloys have been gradually used in recent years as structural materials for equipment and pipelines in the chemical industry due to their good corrosion resistance.

Known for excellent corrosion-resistant properties in chemical processing industry, Zirconium performs outstanding resistance to corrosive attack in most organic and inorganic acids, salt solutions, strong alkalis, and some molten salts.


Grade: Zr 702, Zr 705, UNS R60702, UNS R60705
