Low carbon
Carbon is limited to 0.02% maximum to reduce graphitization risk at elevated temperature.
Low-carbon commercially pure wrought nickel
Nickel 201 Plate, Sheet, Strip and Bar
The low-carbon version of Nickel 200, selected for caustic resistance, conductivity and improved suitability for elevated-temperature service.

Why industrial buyers specify Nickel 201
Nickel 201 retains the corrosion resistance, conductivity and fabrication characteristics of commercially pure nickel while controlling carbon to 0.02% maximum. This low-carbon chemistry helps prevent graphitization and carbon-related embrittlement during prolonged exposure above 315 C.
Caustic resistance
Strong resistance to caustic alkalies and many reducing chemicals.
Conductivity and forming
Useful thermal and electrical conductivity with good ductility and weldability.

Buyer questions
Nickel 201 FAQ
Quick answers for initial sourcing. Confirm critical engineering requirements against the governing specification.
What is the main difference between Nickel 200 and Nickel 201?
Nickel 201 limits carbon to 0.02% maximum, making it better suited to prolonged elevated-temperature service where Nickel 200 can graphitize.
Does Nickel 201 resist caustic alkali?
Yes. Like Nickel 200, it is widely selected for resistance to caustic alkalies, but the actual concentration, temperature and contaminants must be reviewed.
What information is needed for a Nickel 201 quote?
Send product form, standard, dimensions, condition, quantity, operating temperature, testing and MTC requirements.
