In several environments where the corrosion resistance is the most important criteria for material selection, Nickel Alloys are highly recommended.
These alloys also have good mechanical properties.
The corrosion resistance is proved in terms of limited metal loss and in the ability to better withstand localized attack, notably pitting/crevice corrosion, intergranular attack and stress corrosion cracking.
