UNS R60702 Polished Zirconium Bar Stock For Heat Exchanger ASTM B550

UNS R60702 Polished Zirconium Bar Stock For Heat Exchanger ASTM B550

Zirconium Bar Stock is an active metal, which will form an oxide film at room temperature, which makes zirconium and its alloys have excellent corrosion resistance. At the same time, zirconium has good mechanical and heat transfer properties, coupled with significant cost advantages, which makes it an excellent corrosion-resistant structural material in the field of petrochemical industry.
