Nickel 200/201 Round Bar & Rods

Nickel 200 and Nickel 201 round bars and rods are forms of commercially pure wrought nickel with similar properties, though they differ primarily in carbon content. Both offer excellent corrosion resistance and high electrical and thermal conductivity, making them suitable for a wide range of industrial applications. 
Key differences between Nickel 200 and Nickel 201
The main distinction between Nickel 200 (UNS N02200) and Nickel 201 (UNS N02201) is the carbon content, which affects their performance at elevated temperatures. 
Feature     Nickel 200 (UNS N02200)    Nickel 201 (UNS N02201)
Carbon content    0.15% maximum    0.02% maximum
High-temperature resistance    Can be susceptible to intergranular carbon embrittlement at temperatures between 800°F and 1200°F (425°C to 650°C).    The lower carbon content provides superior resistance to intergranular carbon embrittlement above 600°F (315°C).
Applications    Preferred for environments below 600°F (315°C) that require high corrosion resistance, such as chemical and food processing equipment. Also used for electrical components and aerospace parts.    Ideal for high-temperature applications where carbon contamination must be minimized, including chemical plants, thermal processing equipment, and pressure vessel service.
Mechanical strength    Offers slightly higher tensile and yield strength.    Exhibits higher ductility, making it more easily formed and welded.
Common applications
Both alloys are often dual-certified as Nickel 200/201, combining the higher strength of 200 with the high-temperature stability of 201. Round bars and rods made from these alloys are widely used in various industries. 
Chemical processing: Resistant to caustic alkalis and other corrosive substances, they are used for evaporators, reactors, and storage vessels.
Electronics: The alloys' high electrical and thermal conductivity make them ideal for electrical contacts and terminals.
Aerospace: Used in the construction of aircraft and missile components that require corrosion resistance and durability at elevated temperatures.
Marine hardware: Exceptional corrosion resistance makes these materials suitable for use in seawater environments.
Food processing: Used in equipment to ensure product purity.
