Method for manufacturing ferritic stainless steel product
In a method for manufacturing a ferritic stainless steel product, a ferritic stainless steel object is heated in an inert gas atmosphere including nitrogen gas in a heating furnace at a nitriding temperature higher than or equal to a transformation temperature so as to form a nitrided layer on a surface of the ferritic stainless steel object. Moreover, the nitriding temperature is set lower than 1100° C. during the heating. The heating of the ferritic stainless steel object is performed in a state where a solid carbon exists inside the heating furnace.
