Alloy 28 is a high corrosion resistant nickel-iron-chromium alloy containing molybdenum and copper. It offers outstanding resistance to sulfuric acid, phosphoric acid, chloride corrosion and stress corrosion cracking. It is widely used where conventional stainless steels cannot provide sufficient corrosion protection.
