Nickel 201 is a commercially pure nickel with a maximum carbon level of 0.02%. This alloy provides highly ductile mechanical properties across a wide temperature range, and corrosion resistance in neutral to moderately reducing environments. It provides high thermal and electrical conductivity in comparison to nickel-base alloys, stainless and low alloy steels. With its lower carbon content, alloy 201 may be considered for service above 600°F (316°C), where alloy 200 with higher carbon content is not recommended.
