    • PROBLEM TO BE SOLVED: To provide a method capable of stably performing heat treatment even in a low CP (carbon potential) atmosphere.
      SOLUTION: When a steel part is held to a holder, and is heat-treated in an atmosphere satisfying a CP of ≤0.8%, the thickness of an oxide layer formed on the surface of the holder is retained to ≤150 μm. The holder is, e.g., composed of a material having oxidation resistance higher than that of SUS304. Further, when the thickness of the oxide layer formed on the surface of the holder exceeds 150 μm, the oxide layer may be removed from the surface of the holder, or it may be exchanged for a new holder. Stable heat treatment can be operated even in a low CP atmosphere by retaining the thickness of the oxide layer formed on the surface of the holder holding the steel part to ≤150 μm.
