Stainless Steel 316 Round Bars

What Are Nickel 200 and Nickel 201 Round Bars?

Nickel 200 is a commercially pure nickel alloy containing 99.6% minimum nickel, offering excellent corrosion resistance in a variety of aggressive environments.

Nickel 201 is a modified version of Nickel 200 with lower carbon content, providing superior resistance to intergranular corrosion, particularly after welding or high-temperature applications.

Key features of Nickel 200 / 201 round bars:

  • Excellent corrosion resistance in oxidizing and reducing environments
  • Superior resistance to caustic alkalis, organic acids, and seawater
  • High thermal and chemical stability
  • Good mechanical strength and ductility
  • Non-magnetic and easy to fabricate
  • Suitable for welding, forming, and machining

These nickel alloys are widely used in chemical plants, aerospace components, marine hardware, and high-temperature industrial machinery.


Key Features of Nickel 200 / 201 Round Bars

  • High corrosion resistance in both oxidizing and reducing environments
