Alloy 200 Bar

Commercially pure nickel (99.6%) with good mechanical properties and excellent corrosion resistance.

Alloy 200/201 is extremely resistance to caustic alkalies up to and including the molten state. The extra-low carbon content of alloy 200/201 gives virtual immunity to intergranular attack above about 315°C. The presence of chlorates must be kept to a minimum, as they accelerate the rate of attack.

Nickel alloy 200/201 is frequently dual certified as a result of processing which provides the strength of nickel alloy 200 with the stability of the compositional controls of nickel alloy 201.
