Small Diameter Pure Nickel Pipe 6-600mm for Vacuum Coating | Ni200 Ni201 N4 N6 Grades
Material: Pure nickel and nickel alloy
Grades: N4, N6 (Chinese); Ni201, Ni200 (American)
Type: Seamless and welded nickel tubes
Dimensions: Minimum wall thickness 1mm, custom sizes available
- Low density with high specification strength
- Excellent corrosion resistance in harsh environments
- Good heat resistance properties
- Excellent cryogenic performance at low temperatures
- Nonmagnetic and non-toxic characteristics
Commercially pure wrought nickel with high resistance to reducing chemicals. Suitable for oxidizing conditions that form passive oxide films. Excellent resistance to caustic alkalis. Limited to service temperatures below 315°C due to graphitization risk.
Low-carbon version of Nickel 200, designed for applications above 315°C. Resists embrittlement from carbon or graphite precipitation but vulnerable to sulfur compounds at elevated temperatures.
