About Nickel

Nickel 200/201(>99.5% pure) are industrially pure wrought nickel. It offers extensive advantages including outstanding resistance to various corrosive and caustic conditions, alkalis, and acids at the different magnitudes and temperature limits.  Normally, the chemistry constraints of both alloys are combined to result in one alloy that has necessary properties of both. Carbon % is critical for application temperatures above 600oF. Nickel 201 containing lower carbon content prevents graphitization, hence it is more useful at the elevated temperatures above 600oF.

Nickel 200/201 are ferromagnetic in nature. Low electric resistivity. Nickel 201 is approved for pressure vessel construction following ASME Boiler and Pressure Vessel Code for service up to 1250oF.

Nickel 200/201 Applications

Processing and storage of chemicals, synthetic fiber production that include use of sodium hydroxide and fluorine. Aerospace and military, food processing, production of vinyl chloride monomer, viscose rayon and soap, reactors and tubes for handling production and reactions of hydrocarbons. Magnetic actuated devices, spun anodes and laboratory crucibles.

Nickel 200/201 Corrosion Resistance

Nickel 200/201 have low corrosion rates in seawater and rural conditions. Excellent resistance to distilled and fresh waters as well as high speed running seawater. But these are vigorously attacked in stagnant seawater because of local corrosion and fouling. Good resistance to entire dry gases at room temperature. Prevent corrosion by dry chlorine and hydrogen chloride up to 550oC. Nickel 200/201 resist oxidation in the oxidizing media by creating an adherent oxide layer. 

Nickel 200/201 Formation

Any hot and cold processing techniques can be implemented to shape Nickel 200 or 201. The hot processing temperature can be between 1200oF to 2250oF with heavy fabrication to be done at temperatures above 1600oF. Annealing up to 1300oF to 1600oF. Annealing temperature and period should be carefully chosen  as these have great influence on the mechanical properties and structure of a metal. Traditional welding, brazing and soldering methods can be implemented on this alloy. Oxyacetylene welding is not recommended.

These have low annealed hardness and small work hardening rate that is required for cold forming operations like deep drawing, spinning and coining. The outstanding fabrications are advantageous in boats, lab crucibles and electronic parts construction.
