1.Zirconium 702 tube manufacturer. 2.Unique geography resources of BaoJi. 3.Two factories with good production capacity.

    Zirconium is used in services too severe for stainless steels, nickel alloys and titanium or where a significant improvement in service life can be achieved by choosing zirconium instead of less expensive metals or plastic.

    When zirconium is chosen for an application, the high cost and expected serviceability require the chemical composition, mechanical properties and overall casting quality be precisely controlled.

    Zirconium 702 tube  is suitable for environments and applications where the properties of stainless steels are not sufficient.

Feature:

Zirconium alloys have low neutron absorption, high strength and high corrosion resistance under different operating conditions. Unlike stainless steels the texture of a zirconium product will have a significant effect on its performance because irradiation creep, yield strength, and stress corrosion cracking resistance are strong functions of texture.

 

Specification:

YoungLin zirconium tubing (seamless) are available in size range outside diameter 6– 114 mm  with wall thicknesses from 0.5 to 7mm. The zirconium tubes are delivered in straight lengths or as U-bent tubes.

Our company can produce the products as customers' request.

Literature:

Zirconium owes its excellent corrosion resistance to a passivating oxide film (ZRO2) that forms very rapidly on its surface. This film makes the material resistant to virtually all organic acids and alkaline solutions, as well as to mineral acids. Moreover this film is self healing in contact with aqueous media.
