How to tell the difference between mild steel and core 10

I recently had 2 panels laser cut, one of mild steel and one of core 10 and the panels have not been labelled. I don't have time for them to rust to see the difference and the mild steel one I hoped to paint and not let it rust. Can anyone tell me how to tell which one is core 10 and which is mild steel?

Sir:

Perhaps a grind wheel test will do the job. Just take two known samples: 1)mild steel and 2)corten. Put them up to a grind wheel and observe the patterns of sparks that result. Then do the two pannels and see which is which. I suspect that the corten will have a very different spark spray pattern.
