Morphology

hyper-eutectoid + steel

This is a highly technical, domain-specific term: the modifier 'hyper-eutectoid' contains the specialist morpheme 'eutectoid' (not general English vocabulary) and refers to a precise metallurgical composition. Even if a learner knows 'steel' and the prefix 'hyper-', they would not be able to derive the specific meaning (greater than ~0.9% carbon, excess cementite) without subject-matter knowledge, so it is not transparently compositional for a B1 learner.

Etymology

Hyper-eutectoid steel starts with hyper- meaning 'over' and eutectoid meaning the 'right mix' of carbon in steel. So the name tells you it is steel with more than about 0.9% carbon, which creates extra hard particles and makes the steel very hard.
