In search of carbon contamination detection methods

I am looking for a fast any easy method for the detection of carbon contamination on stainless steel (304/304L, 316/316L)without waiting for weeks for rust to bloom, are there such methods available.

I believe this could be done with Glow Discharge Spectroscopy quite nicely. It is a depth profiling technique where the sample is sputtered away layer by layer revealing what elements are present in each layer. The problem is that this equipment is expensive and fairly complex to use. I would recommend paying a contract lab for this type of analysis.
