Steel

The world produces more than 1.8 billion tons of steel a year, releasing nearly twice that weight in carbon dioxide into the atmosphere. It's a huge decarbonization challenge, but steel giant ArcelorMittal is starting on a new green plant in Spain.

MX3D has finally realized its ambitious plan to install the world's first 3D-printed steel bridge over a canal in Amsterdam. The public bridge features integrated sensors to collect data on its structural integrity, crowd behavior, and more.

The steel industry is responsible for around 8 percent of all global carbon emissions annually, and decarbonizing it will require an enormous effort. H2GS plans to lead the way with the world's largest fossil-free steel plant, using green hydrogen.

Electric scooters typically consist of a tubular metal frame, covered with plastic body panels. Swedish startup Stilride is taking what it claims is a more eco-friendly approach with a scooter made from folded sheets of stainless steel.

Chromium is used to make tool steel or stainless steel, and it’s thought to have been invented around the late 19th and early 20th centuries. Archaeologists have now discovered that Persians were mixing chromium into steel way back in the 11th century.

Electronic waste can be difficult to repurpose, as it often consists of two or more mixed materials. Now, however, Australian scientists have developed a method of converting so-called e-waste into a protective coating for steel.

Whenever you try to improve steel, there are usually tradeoffs involved. It’s a balancing act between different properties. Now, engineers have developed a new type of “super steel” that defies this, staying strong while still resisting fractures.

Steel slag is currently utilized both to treat wastewater, and as a concrete aggregate. New research now indicates that using it for the former makes it perform even better as the latter – so the same slag could be used twice.

Back in 2011, we heard about a rather quirky but apparently effective bike lock known as the TiGr. Now, its makers are back with a new version that's more compact and harder to cut through.

Scientists at North Carolina State University have determined that a new composite metal foam should outperform aluminum when used in the construction of aircraft wings.

Rock guitarists sometimes have a strange relationship with their instruments, with many sacrificing them to their art. When Sandvik decided to make an unbreakable all-metal guitar, naturally the company asked fellow Swede Yngwie Malmsteen to try and destroy it.

​A new Kickstarter campaign touting the "world's smallest and sharpest Damascus pocket knife" aims to put the strength of a samurai sword in your trousers. Its makers claim Damascus steel makes not only for a more robust blade, but one that stays sharper than blades made from normal steel.
