Black Oxide (Steam Treatment)

Black Oxide (Steam Treating) is a controlled oxidizing method to provide corrosion resistance. Steam Treating can be performed as a part of the Nitriding cycle, or performed as a stand- alone process.

Key benefits:

  • Improves wear resistance
  • Improves corrosion resistance
  • Provides a uniform blue-black finish

When applied to low and medium density powder metal parts, the oxide film will seal the surface pores. This increases part hardness and compressive strength.
