A new class of advanced steels needs more fine-tuning before use in system components for fusion energy—a more sustainable ...

Pure iron, for example, is very soft. Adding a small amount of tungsten to iron makes tool steel, which is harder than pure iron. Steels are examples of alloys. There are many types of steel.

Ideally, steels and steel-related alloys should be capable of both properties: they should not fragment, for example during processing in a mill or as car bodies involved in an accident.
