Steel

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.

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.

​Ordinarily, steel plants have to regularly halt production while a disposable probe gets lowered into the molten steel, measuring its temperature and collecting samples for chemical analysis. That may not be the case for much longer, though, thanks to a new laser-based inspection system.

​When rain water runs down city streets and into storm sewers, it can be carrying a lot of filth with it – filth such as E. coli bacteria, which may end up in rivers. There could be an inexpensive and efficient new way of ridding the water of that bacteria, however, using chips of waste steel.

Inspired by the internal structure of bones and bamboo, which both boast impressive strength-to-weight ratios, US researchers have created increased the toughness of various metals by altering the microstructures within them.

Scientists have used graphene to create an anti-rust coating for steel.

Self-taught metallurgist Gary Cole has invented a process that produces stell that is lighter and seven percent stronger than martensitic advanced high-strength steel.

Scientists have created a metallic material that can switch back and forth between strong and soft states.

A team of Chinese scientists claim that cigarette butts can be used to protect steel from corrosion.
