The properties of the steel that led it to be more brittle than modern steel was high levels of sulfur, oxygen, and phosphorus, a low level of manganese. “Steel from the Titanic was about ten times more brittle then modern steel when tested at freezing temperature. “The modern and scientific theory at the sinking of the “unsinkable” Titanic shows the continued change in opinion about the cause of the disaster.
