Zusammenfassung:The purpose of the present invention is to reduce the time for manufacturing a steam-treated product such as a blued steel sheet by quickly cooling an object after steam treatment. A method for manufacturing the steam-treated product involves a steam treatment step for introducing steam into an airtight container 10 in which an object 1 to be treated is placed, thereby bringing into contact the steam and the object 1 to be treated, and a treated object cooling step for cooling the object 1 treated in the steam treatment step, and is characterized in that the treated object cooling step is a step in which cooling gas is introduced into the airtight container 10 thereby causing the cooling gas to come into contact with the object 1 treated, and the introduced cooling gas is vented from the airtight container 10.
