Definitions

  • the invention of the application provides the invention as follows.
  • thermomechanical treatment such as the rolling or the forging generally employed in the art, it is not possible to highly accumulate the strain energy or to form a fine texture consisting of ferritic crystal grains 3 ⁇ m or less in grain diameter according to the invention of the present application.
  • the invention of the present application comprises accumulating strain energy at high levels by applying warm intensive working to the high Cr ferritic heat-resistant steel, or forming fine texture consisting of crystal grains 3 ⁇ m or less in grain diameter; however, the protective coating film does not always form at high temperatures in the presence of water vapor by simply accumulating the strain energy by warm intensive working or by forming fine crystal texture. It is necessary to form sequentially thereafter the protective coating film by applying pre-oxidation treatment.
  • the pre-oxidation treatment is preferably carried out under the atmosphere or under an inert gas (rare gas or gaseous nitrogen) atmosphere containing gaseous oxygen, but more practical is to perform the treatment in the atmosphere. Further, the pre-oxidation treatment is preferably performed by heat treatment in the atmosphere at 400 - 800°C for about 30 to 90 minutes.
  • the high Cr ferritic heat-resistant steel of the invention of the application includes those of various compositions containing 15 mass % or less of Cr. For instance, there are included those containing 7 mass % to 15 mass % of Cr.
  • the invention of the application enables forming a thin and highly adhesive oxidation-resistant protective coating film, which had been believed impossible, on the high Cr ferritic steel having a Cr content of 15 % or less.
