The Titanic sinking wasn't caused by the iceberg alone—it was the high-sulfur wrought iron rivets that shattered on impact instead of bending. This video reveals the metallurgical evidence showing how cost-cutting decisions and brittle fracture in freezing water turned a glancing blow into a fatal gash that doomed the unsinkable ship.
