oddly enough, ive come across some rebar that I was certain to be 4140, I didn't shoot it with the pmi gun simply because I didn't want to take the time to borrow it from work, but 25 years of turning metal told me it was most likely 4140.
I agree that each piece of rebar needs tested prior to working it, but sometimes you get a good one.
