Applications of HastelloyB-2
It is widely used in the fields of chemistry, petrochemicals, energy manufacturing and pollution control, especially in the sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid and other industries. It is not recommended to use it in the presence of ferric and divalent copper salts, because these salts will quickly cause corrosion damage. When hydrochloric acid comes into contact with iron and copper, it will react with them to form ferric and divalent copper salts.
