And it was the largest luxury ship in the world which showed the cost of poor choice of materials, inappropriate design and inadequate technology used. Even though a giant iceberg caused the sinking of the Titanic, the inferior materials used in the applications, the incorrect design of the restoration, and the quality irons used in the application forced the ships to sink so quickly. (Reference: RMS Titanic metallurgy, Tim Foecke)Materials used in Titanic applicationsMild steels, manganese sulfide, wrought iron are the materials used in Titanic application found by research. (References: RMS Titanic Metallurgy Tim Foecke). Steel fracture made from hull material recovered from the Titanic wreck site had embedded slag (a byproduct of melting) at a concentration of 9%. But high-quality rivets only contain about 2-3%. The slag helps prevent starching of the iron so that the iron can absorb the load applied in the body. At the same time slag gives the character of brittleness to the iron, so more slag in the iron makes the iron more brittle which makes the iron weaker. Irons with embedded slag were found at the stern and the bow allowed the impact with the iceberg even if it is small... in the center of the paper... coming out of the crash. Recommendation More appropriate design can be achieved with the high technology and equipment we have in the modern world. The bow and stern parts of the naval equipment we have in the modern world. The bow and stern parts of the ship should be designed to withstand enormous amounts of pressure. This will prevent greater pressure from acting on the strong parts of the vessel. To make the steel stronger and reduce the ductile-brittle transition temperature, the transition temperature composition of the steel should reduce the amount of sag (a byproduct of the melting) of 2- 3% Use higher manganese content and lower sulfur content to achieve a higher Mn:S ratio and reduce the ductile-brittle transition temperature by a reasonable amount Lower phosphorus contents, Oxygen and sulfur will also help achieve a lower temperature ductile-brittle transition
