Hi,
This question came up after some stainless steel samples were exposed to high temperatures (metal flame holders in a combustion chamber). Some of them had areas with rainbow colors. What exactly happens to the steel that causes these local rainbows? If the colors in point A and B on the sample are different, does that mean that in point A the steel has been exposed to different temperatures than in point B?
