Zirconium Flanges

Zirconium Alloy 702 UNS R60702 Flanges Manufacturer

Zirconium Alloy 702 Flanges Suppliers In India 

Zirconium Alloy 702 Flanges Exporter In India


Dinesh Tube India is leading manufacturer, exporter & suppliers of high-quality Zirconium 702 Flanges in India as well as all over the world. Zirconium 702 Flanges, available in a variety or grades, materials, and finishes, in metric and inch sizes. Zirconium 702 Flanges (ASTM B493 and B550 & ASME SB493 and SB550) are also known as UNS R60702 which reactive metal that has a high affinity for oxygen resulting in the formation of a protective oxide layer in air at room temperature. The protective oxide layer gives Zirconium alloys their prevalent consumption resistance. This oxide layer can be improved through a warmth treating process. A legitimately shaped upgraded oxide layer serves as an amazing bearing surface against an assortment of materials, grants great disintegration resistance in high-speed frameworks and can enhance the corrosion resistance in certain aggressive environments. Zirconium 702 Flanges are available in welded and seamless forms These Flanges are available in various sizes, shapes as per the requirements of our clients.
