C276 alloy has been widely used in chemical and petrochemical fields, such as components and catalytic systems in contact with chloride-containing organics. This material is especially suitable for use in high temperature, inorganic and organic acids mixed with impurities (such as formic acid and acetic acid), and seawater corrosive environments.
