One of Steel's "powers" is not being knocked off his feet.. I'd imagine there's a limit, but he's been hit by the herald of Gog, who took out both "I can't believe it's not Kingdom Come Superman!" and Hawkman. (The old god Gog, not The Kingdom's version), and even Gog himself didn't knock him down. And he shattered Gog's leg too...
CS, easily.
a.) He was able to slap the herald of Gog around like he was a pathetic feeb -- and just for a point of reference, said Gog-herald has previously been owning all of the JSA'ers, simultaneously. Uber.
b.) Steel's strength even proved sufficient to down 3rd World Gog (the God), with a mere two punches. That is a feat not even the entire JSA combined (inc. KC Superman, Thunderbolt, Alan, etc.) were able to accomplish. Uber.
c.) It's also worth mentioning that just before he put the smack-down on 3rd World Gog, CS shredded off his armor like it was cheap tissue paper -- his armor has a tensile strength of 280,000lbs/sq in, btw. Uber.
^ Those feats were extraordinary, though...
Here CS slaps around herald-Gog (the JSA wrecker):

Again, not even the combined JSA (inc. KC Supes/Thunderbolt/Alan/etc.) could do that:

And here's proof that it has a tensile strength of 280,000 lbs/sq in:

See? I didn't exaggerate or anything. 😉
