Steel has always been around,he was from Superman death till after the doomsday wars pre flashpoint,to helping during the new 52,till now being with Lana in the Rebirth books.
I never saw him as DCs iron Man,cause iron Man is all about high tech this or that,while Steel almost came off like a guy who put on armor and flight boots and went out to bust ppls **** in.that might be a extreme oversimplification on my part.
