PROBLEM TO BE SOLVED: To provide a method of manufacturing a stainless steel for a solid oxide fuel cell capable of sufficiently demonstrating oxidation resistance which the stainless steel for the solid oxide fuel cell has, especially by optimizing a firing condition in a cold rolling process.SOLUTION: There is provided a method of manufacturing a stainless steel for a solid oxide fuel cell in which firing in a preceding process of finishing cold rolling or a post-process of finishing cold rolling is conducted using hydrogen as a major component and under atmosphere containing nitrogen of 0.01 vol.% or less at 700 to 1100°C, preferably hydrogen atmosphere is an atmosphere containing 99.999 vol.% or more of hydrogen and 0.001 vol.% or less of nitrogen. |
