Hastelloy C276 is a nickel based alloy that has chromium, molybdenum, etc., in its chemical composition.The Hastelloy C276 round bar shows good resistance to corrosion along with high ductility, weldability and formability.It can also withstand chloride ion related stress corrosion cracking.They are easy to fabricate using standard techniques and the material is quite versatile.EN 2.4819 rounds can also resist pitting and crevice corrosion.
The Hastelloy c276 annealed bar shows good resistance in oxidizing and reducing environments.They are used in flue gas desulfurization systems.The 2.4819 Hastelloy hot rolled bars can withstand a wide range of chemical environments, like organic and inorganic media.They can also resist seawater and brine solution.The Hastelloy alloy c276 cold drawn bar can work in chlorine gas and dioxides.
The Hastelloy C276 rod shows some unique properties and benefits, which are listed below:
