Sandvik Zr 702 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.

Sandvik Zr 702 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

Sandvik Zr 702 is used in environments where even the best stainless steels are not sufficiently corrosion resistant. Zirconium is in many cases the ideal choice from both technical and economical point of view (the price/life time relation).
