led the e-commerce department staff to participate in the [Steel Knowledge Classroom] training. When the teacher Yang lectured, the audience only heard the sound of the photo. The learning atmosphere is particularly strong. In this course, Xiao Bian finally understands the mystery of the Titanic sinking, which is actually a steel plate material problem.
One day in April 1912, the Titanic, known as "never sinking", suffered a shipwreck. When the ship sailed, it had a death kiss with the iceberg. The starboard side of the hull was torn open by an iceberg below the sea level. The mouth, the rivet of the front line of the ship broke, and the cargo compartment began to infiltrate into the seawater quickly. Why did the “never-sinking wheel sink after three hours of hitting the iceberg”?
In February 1995, R Gannon published an article in the American magazine "popular science". He answered this unsolved mystery that has plagued the world for more than 80 years. In the early years, the Titanic used a steel plate with a high sulfur content. The toughness is very poor, especially at low temperatures. This is the crux of the rapid sinking of the Royal Cruise.
In layman's terms, the steel plate contains too much phosphorus and sulfur, which leads to poor toughness (flexibility) of the steel plate. The steel plate will be brittle at low temperatures. If the Titanic is facing the iceberg, The possibility of breakage is negligible, but the hull is indeed hit by an iceberg. In the case of such low-temperature seawater, the brittleness of the hull steel plate is particularly noticeable, resulting in fracture.
