Gardens of stainless steel
Located outside the Chinese city of Nanjing, the Jiangsu Garden Expo recreates famous classical gardens from across Jiangsu province. The 3.5 km2 park is an outstanding example of regenerating a degraded environment into a living museum furnished with hotels, restaurants, and entertainment. Stainless steel features prominently throughout the Expo.
Molybdenum in magnetically shielded rooms
Detecting nature's tiniest magnetic activity for medicine and research relies on suppressing a constant barrage of external magnetic influence. For decades, a molybdenum-containing alloy called mu-metal has been used as a magnetic shielding material due to its ability to divert both the Earth's natural magnetic field and manmade sources. Today, rooms clad in layers of mu-metal and similar alloys provide unfathomable levels of magnetic shielding for procedures that save lives and extend the frontiers of science.
Nant de Drance: a gigantic rechargeable battery
Generating electricity when the sun does not shine or the wind does not blow poses a challenge for the world's transition to renewable power. A twist on a century-old technology offers an elegant solution. Pumped storage hydropower uses gravity to store massive amounts of green energy and generate electricity on demand. At Nant de Drance in the Swiss alps, molybdenum-alloyed high strength steels are crucial to keep electricity flowing.
Sluice gates brave the shifting tides
Sluice gates are movable barriers that regulate water levels and flow rates in waterways. In a world of changing climate and increased flooding risks, these gates need to be taller and stronger than ever before. Thanks to their strength and corrosion resistance, molybdenum- containing duplex stainless steels are the ideal construction material.
Printing a stainless steel dragon
Most 3D printed objects are less than 30 cm long. So, how is the 10 m long Oregon Dragon Bench possible? Instead of using powder, the bench was built layer by layer applying a robotic welding technology called "WAAM". Made with 2209 duplex stainless steel weld wire, the Oregon Dragon Bench exemplifies how 3D printed metal structures can do more with less.
