Sandvik Zr 702 Zirconium
Categories:	Metal; Nonferrous Metal; Zirconium Alloy
Material Notes:	In environments where even the best stainless steels are not sufficiently corrosion resistant, titanium, zirconium and tantalum can be used in many applications. Of these titanium is normally the least expensive and tantalum the most corrosion resistant material. Zirconium is in many cases the ideal choice from both technical and economical point of view (the price/life time relation). Zirconium 702 is characterized by: High heat transfer efficiency Very low thermal expansion Immunity to 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 Information provided by Sandvik ASTM B523
