PROBLEM TO BE SOLVED: To provide a corrosion inhibition method for enabling carbon steel or stainless steel in general use such as type 304 and type 316 to be used, without requiring a complex utility such as an external power source, when an equipment consisting of carbon steel or stainless steel in general use deals with strongly corrosive sulfuric acid or a solution including sulfuric acid. SOLUTION: This method includes contacting a part of the equipment made from carbon steel or stainless steel with a noble metal (such as platinum, gold, or silver) in a sulfuric acid solution or a solution including sulfuric acid, or making ions of these noble metals exist in the solution. |
