Diamond blades dislike cutting steel, as I've found over 30 years of concrete cutting with them. The blade periphery get so hot that the diamonds break down and lose their cutting edges. Then the blade starts to 'hammer' in the cut which is the cause of the heavy vibration. In extreme cases the segments start to melt and they even go out of round.
I suspect that the 'metal cutting' discs are simply made with a softer bonding matrix so that they erode more quickly thus exposing fresh diamonds. Either way I think they're a poor substitute for a decent carbon blade.
