LISTEN: Steelmaker's Skeleton to Save Historic Ship From Crumbling

Alleima is a Swedish steelmaker that makes products out of advanced stainless steel and special alloys. The company, formerly Sandvik Materials Technology, was officially spun out of Sandvik in 2022 and has more than 900 active alloy recipes. The company typically makes seamless steel tubes for the energy, chemical and aerospace industries, precision strip steel for white goods and even ultra-fine wires for medical and micro-electronic devices. The company recently found itself facing a unique challenge: the crumbling remains of a nearly 400-year-old ship. On August 10, 1628, the Vasa cast off from below Tre Kronor castle in Stockholm and left the harbor. She was a mighty ship with three masts that could carry ten sails, measuring 52 meters from tip to keel and 69 meters long, it weighed 1,200 tons. The Vasa was hit with a mighty gust from the gods that caused her to capsize. Water poured in through open gun ports, the Vasa sank to the floor of the sea, and at least 30 of the 150 or so people aboard perished.
