ASTM B462 C-276 Weld neck FLANGE,UNS N10276 Hastelloy C-276 WNRF Flanges
Hastelloy C-276 has a excellent resistance to localized corrosion, stress corrosion cracking, oxidizing and reducing media, which is suit for a wide variety of chemical process environments, including ferric and cupric chlorides, hot contaminated media (organic and inorganic), formic and acetic acids, seawater and brine solutions. Meanwhile, Hastelloy C276 is the few kinds of material that can withstand the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide.
Alloy C-276 is a solid solution strengthened nickel-molybdenum-chromium alloy with a small amount of tungsten. Alloy C-276 exhibits excellent corrosion resistance in a variety of harsh environments and media. Like many other nickel alloys, it is ductile, easily formed and welded.
Weld neck flange is one of the popular components in piping systems, known for their robust design and reliability in high-pressure and high-temperature applications. They feature a tapered hub that facilitates smooth fluid flow and reduces turbulence at the joint. This type of flange is welded to the pipe, ensuring a strong and permanent connection that enhances structural integrity.
