Hastelloy B2 Flanges

what is a hastelloy b2 flange?

Hastelloy B2 Flanges are commonly used in applications that require resistance to corrosion and high temperatures, such as chemical processing, petrochemical, and oil and gas industries. These flanges are designed to connect pipes or other components together, and they come in various shapes and sizes to suit different needs.

The main advantages of using Hastelloy B2 Flanges include their high strength, resistance to corrosion and high temperatures, and their ability to withstand extreme environments. These flanges are also known for their excellent weldability, which makes them easy to install and maintain.

Hastelloy B2 Flanges are made from a nickel-molybdenum alloy called Hastelloy B2, which has the following composition:

Nickel (Ni): 65%

Molybdenum (Mo): 28%

Iron (Fe): 1-2%

Chromium (Cr): 1%

Silicon (Si): 0.10%

Carbon (C): 0.02%

Cobalt (Co): 0.5%

Manganese (Mn): 1%

Phosphorus (P): 0.04%

Sulfur (S): 0.03%

Hastelloy B2 Flanges are available in various specifications to meet different industry needs. Here are some common specifications for Hastelloy B2 Flanges:
