这是什么?
A metal that makes steel much stronger when added in tiny amounts — a few hundred grams per tonne changes the whole alloy.
为何重要?
High-strength low-alloy steel with niobium lets pipelines, bridges and car bodies use less metal for the same strength. It is also the superconductor in MRI magnets.
