Hastelloy C-276 is a kind of Ni Cr Mo alloy containing tungsten, with very low silicon carbon content. It is considered to be a universal corrosion-resistant alloy. It has good resistance to local corrosion, stress corrosion cracking, oxidizing and reducing media. It can be used in many chemical conditions, such as ferric chloride, copper chloride, heat polluted solution (organic and inorganic), formic acid, acetic acid, etc Seawater and saline solution. It is one of the few materials that can resist the corrosion of wet chlorine, hypochlorite and chlorine dioxide.
