Morphology

mild + steel

A B1 learner who knows 'mild' (not severe/strong) and 'steel' (the metal) can reasonably infer that 'mild steel' means a relatively soft or less hard type of steel that is easy to shape, so the core sense is compositional. However, the precise metallurgical meaning (specific low carbon content and technical properties) is specialized and not fully predictable from the words alone, so the expression is only partially transparent.

Etymology

The term mild steel comes from the older use of mild to mean 'not strong' or 'soft'. So mild steel is literally a softer kind of steel, which is why it refers to steel with little carbon that is easy to shape and weld.
