Nickel 200 plate is one of the most trusted materials when corrosion resistance and long-term reliability are non-negotiable. In caustic soda processing plants, offshore marine structures, and demanding energy systems, the material must survive aggressive chemical exposure, temperature variation, and mechanical stress. Nickel 200 delivers that balance in a simple yet highly effective way.
At DLX, we supply corrosion-resistant Nickel 200 plate designed for industrial environments where stability, purity, and consistency matter more than short-term cost savings.

Nickel 200 is commercially pure wrought nickel, typically containing a minimum of 99.0% nickel. Its low carbon content provides excellent resistance to corrosion, particularly in alkaline environments such as caustic soda processing.
This grade is widely recognized for:
-
Outstanding resistance to caustic alkalis
-
Strong corrosion resistance in marine atmospheres
-
Good thermal and electrical conductivity
-
Excellent mechanical properties at moderate temperatures
-
Reliable weldability and formability
Unlike complex alloy systems, Nickel 200 relies on its high nickel purity to deliver stable chemical performance. That simplicity is often its biggest strength.
