CEWELD® E NiCro 825 is used for welding alloy 825 and other nickel-iron-chromium-molybdenum-copper alloys of similar composition. The weld metal is highly resistant to corrosion, especially in reducing chemicals such as sulphuric acid and phosphoric acid. It is also suitable for cladding carbon steels and low-alloy steels. Applications include pressure vessels, piping, heat exchangers, valves and other components for the chemical processing, offshore and oil and gas industries.

CEWELD® E NiCro 825 has excellent weldability with a fully austenitic weld metal that exhibits high resistance to stress corrosion cracking and pitting in media containing chloride ions. It shows good corrosion resistance to reducing acids due to the combination of Ni, Mo and Cu. Sufficient resistance to oxidizing acids. The weld metal is corrosion resistant in seawater.
