:Here's a direct quote from the article cited. "The steel used in constructing the RMS Titanic was probably the best plain carbon ship plate available in the period of 1909 to 1911, but it would not be acceptable at the present time for any construction purposes and particularly not for ship construction. Whether a ship constructed of modern steel would have suffered as much damage as the Titanic in a similar accident seems problematic. Navigational aides exist now that did not exist in 1912; hence, icebergs would be sighted at a much greater distance, allowing more time for evasive action. If the Titanic had not collided with the iceberg, it could have had a career of more than 20 years as the Olympic had. It was built of similar steel, in the same shipyard, and from the same design. The only difference was a big iceberg."
