Product Features

B-3 alloy is a new member of the nickel alloy family, which has excellent corrosion resistance to hydrochloric acid at any temperature and concentration. It also has good corrosion resistance to sulfuric acid, acetic acid, formic acid, phosphoric acid, and other non oxidizing media.

Due to the adjustment of its chemical composition, its thermal stability has been significantly improved compared to the original B-2 alloy. B-3 alloy has high resistance to pitting corrosion, stress corrosion, knife edge corrosion, and corrosion in the heat affected zone of welding.

Application scope and field

B-3 alloy is suitable for all previous applications of B-2 alloy. Like B-2 alloy, B-3 is not recommended for use in environments with trivalent iron salts and divalent copper salts, as these salts can quickly cause corrosion damage. When hydrochloric acid comes into contact with iron and copper, it undergoes a chemical reaction to form trivalent iron salts and divalent copper salts.
