What Are Hastelloy X Flanges?
Hastelloy X Flanges are piping components used to connect pipes together as well as connect other equipment such as pumps and valves and equipment together. They are made of a nickel-chromium-iron-molybdenum alloy, which offers excellent resistance to heat and corrosion.
Excellent resistance to oxidizing, reducing and neutral media and superior carburization and thermal fatigue resistance which allow it to be used in high-temperature systems are due to significant amounts of chromium, molybdenum and iron.
