What are the trim rings for A Body Rallye Wheels made of

Good morning....been having a look to see if I can get an answer to this question. Not sure if they are solid stainless steel or if they are chromed....I have some curb rash on one I'd like to attempt to remove but thought I should verify what I am working with beforehand. Any suggestions as to how best to remove? Some are light that would probably buff out with polish...some are deeper and may require some sanding...Thoughts? With thanks.
