This invention provides a method for analyzing the highest temperature experienced by 304 stainless steel and its components. When 304 stainless steel and its components operate in an air atmosphere and high-temperature environment, their surface undergoes high-temperature oxidation, producing an extremely thin and dense colorless and transparent oxide film that exhibits interference colors. The color of these interference colors is related to the thickness of the oxide film. After a certain period of high-temperature oxidation, the thickness of the oxide film produced by the 304 stainless steel and its components is related to the highest temperature experienced. The L* and a* values ​​of the surface color of the 304 stainless steel and its components are measured using a spectrophotometer. These values ​​are then substituted into the formula provided in this invention to calculate the highest temperature experienced by the 304 stainless steel and its components. The advantages of this method are: no prior test preparation is required; no observation is needed while the 304 stainless steel and its components are in operation; and it is non-contact, thus not damaging the surface of the test object.
