However, when the above-mentioned polished stainless steel sheet is used in an environment of 200 to 500 ° C., the surface discolors dark brown or dark blue, and the appearance is significantly impaired. This discoloration is called temper color, which is only discolored initially, but if the discoloration proceeds as it is, rust resistance may deteriorate and rusting may occur.

A method of performing bright annealing finish is known. However, adding a large amount of Si or Al to stainless steel causes a decrease in toughness,
The hot workability also deteriorates. Further, in the conventional industrial process, various polishing finishes are performed after bright annealing, but after the polishing finish, the temper color resistance is almost the same as that of a normal stainless steel sheet.

Therefore, it has been found that it is necessary to form an oxide film rich in Cr, Si and Al components.

The atomic concentration ratio (Cr + Si +

Analysis by (Auger electron spectroscopy), the temper color resistance was heated at 250 ° C. for 5 hours in the air, and the change in color before and after heating was determined by a color difference (ΔE * : JIS Z 8730).

えることから好ましくない。If ΔE * is 4 or less, discoloration is not noticeable, so that the surface has an atomic concentration ratio (Cr + Si + Al) / Fe of 0.
It became clear that it is necessary to form an oxide film of 6 or more. The atomic concentration ratio (Cr + Si + Al) / Fe in the as-polished surface oxide film is 0.1 to 0.2, and the temper color resistance is remarkably poor as it is. Therefore, the inventors of the present invention performed bright annealing on the surface of the polished finished steel plate to obtain Cr, Si, and Cr at a depth of 50 Å from the surface.
A method for improving the temper color resistance by forming an oxide film having an atomic concentration ratio of Al and Fe (Cr + Si + Al) / Fe of 0.6 or more was examined. However, in the conventional process, there is an annealing step before polishing and finishing. Further, if bright annealing is further performed, the product material such as mechanical properties may be largely deviated from the target, stable manufacturing conditions are difficult, and the number of steps is increased, which is not preferable.

203 No. FIG. 2 shows the results of bright annealing at various annealing temperatures T1 (° C.) and atmospheric dew point T2 (° C.) after mechanical polishing corresponding to 5349). The annealing temperature is plotted on the horizontal axis and the atmospheric dew point is plotted on the vertical axis. The atomic concentration ratio of Cr, Si, Al, and Fe (Cr +
Si + Al) / Fe is sought, and the range where the atomic concentration ratio is stably 0.6 or more is 750 ≦ T1 ≦ 5 · T2 + 1200 ... −70 ≦ T2 ≦ −30.

い。When the temperature T1 (° C.) of the bright annealing is less than 750 ° C., the diffusion movement of the effective elements (Si, Al) centered on Cr is delayed, and the oxide film having a sufficient atomic concentration ratio cannot be obtained. If the temperature exceeds (5 × T2 + 1200) ° C,
The condition for reducing Cr is that the oxidation and diffusion transfer of Cr are suppressed, and the diffusion transfer of other elements is also suppressed.
However, since the annealing temperature under the Cr reduction condition is determined by the relationship with the dew point, the bright annealing temperature T1 (° C.) is preferably in the range of the formula. It is preferably 800 ° C. or higher and 1000 ° C. or lower.

Concentration of e cannot be avoided and stable quality cannot be obtained. A gas dew point below -70 ° C is very difficult industrially. Therefore, the dew point of bright annealing should be within the range of the formula. It is preferably -60 ° C or higher and lower than -35 ° C.
