Steel

Different types of metal have different qualities, so combining them can result in items that outperform those made of any one metal. A new technique now allows such mixing to be performed by 3D printers, faster and easier than ever before.

Strength and flexibility are two opposites that usually need to be balanced in steel. But now engineers at Purdue University and Sandia Labs have developed a new treatment that can be applied to steel alloys to boost both strength and ductility.

Back in 2020 we first heard about the SUS1, a prototype folded-steel electric scooter made by Swedish startup Stilride. Well, the company has now announced full specs and pricing on the production version of the vehicle, called the Stilride 1.

A new archeological discovery has confirmed that tempered steel was used by artisans in the Iberian Peninsula to carve intricate motifs into hard rock stelae during the Final Bronze Age, earlier than previously thought.

A rare decarbonization idea that looks as good for business as it does for the planet. This system promises to radically reduce carbon dioxide emissions for 70% of steelmakers, while generating profits and making use of existing blast furnaces.

The German steel giant is investing $1.9 billion in a hydrogen-powered direct-reduction system that can create high-quality steel without needing the rare, high-grade iron ore required by most green steel processes. This could open the floodgates.

As useful as steel is, its main weakness may be its vulnerability to corrosion. Researchers in Korea have now developed a new alloy coating that boosts steel’s resistance to rust, by adding a simple extra step in the surface treatment.

Scientists at Rice University have cooked up a new alloy with a unique and diverse set of attributes that could prove highly effective at protecting steel from corrosion, and can even heal itself when damaged.

Back In August we saw the world's very first "fossil-free" steel delivery makes its way to Volvo in Sweden, which the automaker has now fashioned into a mining lorry as a beacon of greener vehicle construction.

A milestone in decarbonization today as Sweden's SSAB made the world's very first "fossil-free" steel delivery, created with green hydrogen instead of coal and coke, to a customer, Volvo, where it will be used in electric trucks.

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.
