ASTM B564 UNS N06625 Inconel 625 Flanges

Check Alloy 625 Flanges Chemical Composition And Most Reliable Manufacturer Of UNS N06625 Blind Flange.

The Inconel alloy 625 has been used in the marine and petroleum industry for a long time. The main characteristics of Inconel 625 Flanges are high strength, fracture toughness, fabricability, and corrosion resistance. In addition, the Alloy 625 Flanges have shown excellent resistive properties in the seawater, both stagnant and flowing. The ASTM B564 N06625 Inconel 625 Pipe Flanges also comes with excellent operability. Along with their corrosion resistive properties, these flanges have a wide range of applications in nuclear aerospace, chemical processes, etc. To have the right balance of all the properties in ASTM B564 2.4856 Weld Neck Flange, all the hot and cool parts of the flange must be annealed and cooled rapidly. Also, the ASTM B564 Inconel 625 Socket Weld Flanges can be welded easily using any standard processes used for austenitic steel, like fusion and resistance methods.

We are one of the top producers of Inconel 625 Blind Flange in India, who are known for supplying quality products. Depending on the client's requirements, we can customize the UNS N06625 Slip On Flange dimensions. Our products are delivered all over India, and even to international clients in different parts of the world.
