Product FEATURE
1. B-3 alloy is a new member of the nickel alloy family, it has excellent corrosion resistance to hydrochloric acid at any temperature and concentration, as well as good corrosion resistance to sulfuric acid, acetic acid, formic acid, phosphoric acid, and other non-oxidizing media.
2. Due to the adjustment of its chemical composition, its thermal stability has been greatly improved compared with the original B-2 alloy. B-3 alloy has high resistance to pitting corrosion, stress corrosion, cutter corrosion and corrosion in the heat affected zone of welding.
application
B-3 alloy can be used in all applications of the previous B-2 alloy. Like B-2 alloy, B-3 is not recommended for use in environments where trivalent iron and divalent copper salts are present, as these salts can quickly cause corrosion damage. When hydrochloric acid comes into contact with iron and copper, it chemically reacts with them to form trivalent iron and divalent copper salts.
