Corrosion Resistance

The composition of Nickel 600 provides corrosion resistance in a wide range of corrosive environments. The addition of chromium provides superior corrosion resistance in acidic environments, compared to a pure nickel, while allowing the material to maintain corrosion resistance in a reducing state and exhibit superior corrosion resistance to alkaline solutions. Nickel Alloy 600 is also highly resistance to stress-corrosion cracking.
