Valve material instruction:



Zirconium is highly resistant to a wide range of acids and bases, both organic and inorganic, which makes it an interesting and exceptional long-life alternative to other materials in highly demanding applications. 



Zr **2 is a zirconium grade characterized by immunity to stress corrosion cracking and high resistance to pitting and crevice corrosion. The grade has very good corrosion resistance in most organic acids, excellent corrosion resistance in mineral acids, good corrosion resistance in strong alkalis and moderate mechanical strength.

 

Zr **2 main characteristics:

High heat transfer efficiency

Very low thermal expansion

Immunity to stress corrosion cracking (SCC).

High resistance to localized (pitting and crevice) forms of corrosion

Very good corrosion resistance in most organic acids

Exceptional corrosion resistance in mineral acids

Good corrosion resistance in strong alkalis
