The fragility of the steel is a very valid point, however by the standards of the day, Titanic had high quality steel - so while relevant, any ship of the time, would have had the same issue. I am however quite skeptical of the claim in that link that Titanic would have remained afloat for 6 hours had there been not watertight compartments - various marine architects have done simulations and have determined that the ship would have capsized or rolled over onto its side well before that point - beyond that, the ship would have lost lighting between 45 min, and one hour after collision, creating a panic situation as well.
