Forging 5-Inch Armor: How Submarine Steel is Actually Made
At 2,000 feet down, the ocean can crush ordinary steel like a tin can. Today, we go inside the ultra-secure heavy industrial plant where engineers forge 5-inch thick submarine armor. From the 3000°F electric arc furnace to vacuum degassing and medical-grade ultrasonic scans, we reveal how the world's toughest metal is built to survive the crushing pressure of the Atlantic Ocean.
