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.
Zirconium welding wire 702, 705 UNS R60702 60705 can be made according to standard ASTM B550/B550M-07 and standard AWS A5.24/ A5.24M:2005
Zirconium Wire, Zirconium Welding Wire , Zirconium Alloy Wire,
Zirconium wire is one of our main products.It is available in varying
Diameters ,from 0.001" to 0.236". We produce in accordance with customers'
requirements. In addition to the following grades
Zirconium welding wire diameter ( 0.8mm, 0.9mm , 1.0mm , 1.2mm , 1.6mm , 2.4mm)
Product application:
mainly used in pressure vessels, petrochemical, aerospace, marine engineering, hydrogenation reactors and other fields.
Product characteristics:
Zirconium welding wire has excellent corrosion resistance, it has very good corrosion resistance to most organic acids, inorganic acids, strong alkalis and some molten salts. Hydrochloric acid, nitric acid, and organic acids near 100 ° C have no effect on zirconium. Zirconium has better corrosion resistance in alkali than titanium, tantalum, niobium, and stainless steel, and has good heat resistance and processability. Therefore, in the industrial And chemical industry has been widely used.
