Because the 925 nickel bar offers excellent corrosion resistance in both oxidizing and reducing environments, the grade has proven useful in many "sour" applications in oil and natural gas applications.  It has been used in down-hole and surface components including valves, hangers, tool joints, fasteners, shafting and high strength piping systems.

925 nickel bar may be machined in either the solution annealed or aged condition.  Best results are often obtained by rough machining in the solution annealed condition and finishing after heat treatment.  Cemented carbides generally produce the highest cutting rates and are recommended for most turning operations involving uninterrupted cuts.  High speed steel tools may be used for interrupted cuts, finishing to close tolerances and cutting with the least amount of cold work hardening.

Typical stock removal rates:

  • 40-50 ft/min with high speed steel in the annealed condition
  • 15-20 ft/min with high speed steel in the aged condition
  • 175-200 ft/min with carbide tools in the annealed condition
