Nickel 200 (UNS N02200)

Nickel 200 (UNS N02200) is a wrought commercially pure nickel with a maximum carbon level of 0.15%. This alloy provides highly ductile mechanical properties across a wide temperature range. It provides corrosion resistance in neutral to moderately reducing environments. Nickel 200 is ferromagnetic. It provides high thermal and electrical conductivity in comparison to nickel-base alloys, stainless and low alloy steels. Nickel 200 is not recommended for service above 600°F (316℃) because long-time exposures in the 800°F to 1200°F range result in precipitation of a carbon containing phase and loss of ductility.
