Standard AWS A5.24 Zirconium Welding Rod With Black / Polished Surface
Zirconium Welding Rod 1.6mm/2.4mm/ 3mm standard AWS A5.24
Zirconium is resistant to boiling points in sulfuric acid and higher than the boiling point. Its concentration can reach 70%. Zirconium can resist certain highly corrosive environments including various inorganic acids (hydrochloric acid, sulfuric acid, nitric acid, etc.), alkalis, and most organic acids (such as hydrochloric acid , Formic acid, etc.) of various salt solutions and molten alkali. Corrosion resistance in sodium hydroxide medium is the same as nickel.
