It just depends on the hardness of the steel you cut vs the hardness of your saw chain and the chain speed, feed rate, and sharpening angles. I was testing a saw and saw a knot in the dryish white oak I was cutting, and sure enough felt some chatter. It was a harder knot than usual, but not outside of what I'd expect possible when sawing wood. Then I noticed it seemed to be cutting slower after the "knot".
I have bumped the side of a trailer with a saw and it took nice chips out of the steel without dulling the chain.
