Chinese scientists have developed a new ultra-strong steel

A team of researchers from several institutions in China and Taiwan announced that they have succeeded in inventing a new type of steel, which, compared to traditional industrial steel, has significantly higher strength and ductility. In the scientific journal Science, the team described part of the process of working on this steel and highlighted some details regarding the chemical composition of their new material, however, without giving some other details from the calculation of the capitalization of their labor. Noting their results, the scientists stated that their material may well become a complete and uncontested replacement for conventional industrial steel.

While conventional steel is made in one of two directions – either more ductility or more strength – the improved steel material differs from the presented researchers in a very unusual approach to use. They claim that they have managed to find a way to avoid significant “kink” in the direction of strength or ductility by updating the chemical composition of their steel.

For the manufacture of their material, the scientists used a proprietary technology called D&P – details were not disclosed, but they indicate that such technology is used to create ultra-strong steel for industrial purposes. As for the chemical composition of its steel, it is known to be a medium manganese steel made with 0.47% carbon, 10% manganese, 0.7% vanadium and 2% aluminum.

The researchers also reported that in the process of making such steel, the so-called cold rolling process is used, followed by a systematic and constantly increasing temperature rise around the material – and at a certain point, scientists “attach” metastable austenite grains, which allows the ultra-strong steel to return to its former plasticity and even further increase it. More detailed details are not yet available, as the developers want to conduct further tests with their new material.
